I’ve been to Zahrabel many times and this was my first visit after Covid-19. The food was still excellent (I’d forgotten how good it tasted after a few months of social distancing). Service and atmosphere were wonderful, perfect for catching up with family and friends. This place was a wonderful introduction to Lebanese food for someone like me who is used to Chinese cuisine.

While the food is kind of decent, the service at this place is terrible, inexperienced and arrogant waiters.They are always on booking app at 50% off, but even with the discount, I would say don't bother.We were almost alone in the dining room, doesn't seem like they will survive much longer under such business environment

It was an amazing experience ,the atmosphere and vibe is very warm and welcoming . The food was top notch , had the 6 dishes sharing platter . All the dishes were delicious , they were made with love and care . Would really recommend the Jos mahrouse and Batata harra as an appetizer . All the main course dishes are equally yummy . But personally I loved the chicken elmina and lamb kebabs. They were so juicy and tender. They'd just melt in your mouth . If you are looks for authentic Lebanese good

Saturday dinner. Just cutting the laziness and going away from Central to dine, I looked up on Eatigo and Zahrabel in Wanchai popped up with a 50% discount. And it was booked. Middle Eastern, Lebanese is a fool-proof pick always.

I didn't read the fine print to realize until they told us that it was only the sharing menus for the Eatigo discount. The good part was that they didn't charge the child.

You have options to select 4, 6, 8 or 10 dishes and it could be a mix and match from any sections - the hot, the cold, the entrees.

We did the usual hummus, baba ganoush, falafel, their nut dip. Besides the usual, we did the Arnabit Batata b’il Tahini - which was seasoned crispy cauliflower florets and spiced potatoes in a rich tahini sauce and a Vegetarian Fousulieh - a hearty and robust Lebanese bean stew, served with Lebanese rice.

The hummus, baba ganoush and their nut dip were all good. Their falafels - which they only got two - were probably the best-tasting falafels in Hong Kong and one of the best I've eaten, ever. The aromatics were better than any I've had.

My only question to the restaurant or the hospitality industry here - I understand you're portioning it for two, which means one for each (which by default wasn't enough), but you know there's a kid on the table. Would it break your bank if you served three pieces of falafels instead of two?

I'm a fan of well seasoned foods, extra seasoned foods, but the Arnabit Batata b’il Tahini felt a bit too much for me. Or that, sided with labne or cacik might've made it perfect by cutting through the herbs and spices of the cauliflower and the potatoes.

The bean stew was primarily red and light brown kidney beans. Seasoned to perfection. The rice and vermicelli could've been a bit more crunchier, but no complains there.

Overall, the portions were quite little, I thought. But I the flavours were spot on. The presentations were great!

Coffee or tea and mini desserts are included in the tasting menu and they were great too. Especially that muddy, spiced coffee.

My arak based cocktail was cloyingly sweet with the date syrup. I'm not sure if they used too much of the syrup or paired it with the sweeter version of the arak, but it was too sweet for me. And I don't say that often. But if there's anything anise based, I got to have it. Kesak!

Exceeded my expectations. The mezzes are deliciously light and fine. Service is attentive on top of the food. The lamb and chicken kebabs, kafta, signature dips, kibbeh, and date fingers and baklava satisfied my food cravings. Will definitely be back for more!

Went for dinner four of us. Signature cold mezze is a secret family recipe and a must try, hot mezzes are ok, huge portions. Although food and service was good, the restaurant layout and environment doesnt invite to stay relax and allow for a quiet conversation.

The waiters are all very friendly and genuine. The food itself is great! One of the best that I’ve tried in Hong Kong and comparable to those in London. Bread keeps coming. The roasted cauliflower is fantastic. The desserts are so not too sweet and it comes with mint tea. They also let us try a selection of their wines. Ended up giving $200 tips for a table of 2. Thank you for the lovely service!

Summary: Delicious and refined (not an easy task) Lebanese food in an inviting setting, though at a slightly higher price point than you might be used to. Still worth every penny and guarantee whoever you bring will enjoy it. Great for a date or business dinner.I maintain that one of Hong Kong’s better foreign cuisines is Middle Eastern – almost every place I’ve visited is at least pretty good (besides Sahara which was… bad), and some I really enjoy: e.g. Le Souk, Sultans Table, and Awtar.

Summary: Delicious and refined (not an easy task) Lebanese food in an inviting setting, though at a slightly higher price point than you might be used to. Still worth every penny and guarantee whoever you bring will enjoy it. Great for a date or business dinner.

I maintain that one of Hong Kong’s better foreign cuisines is Middle Eastern – almost every place I’ve visited is at least pretty good (besides Sahara which was… bad), and some I really enjoy: e.g. Le Souk, Sultans Table, and Awtar. Zahrabel though, might be the best of them all.

On the 25th floor of the Wanchai building with Pirata and Optimist (side note: those places have really declined haven’t they?), Zahrabel’s floor-to-ceiling windows allow a classic HK view of the buildings directly across the street, though with the warm lighting and expansive tables, the somewhat isolated ambience works. Service is generous and knowledgeable, with great recommendations for food and helpful samplers of dishes and wine we weren’t familiar with. The restaurant was over half-full but I never had to pour a glass of wine for the table, the servers were so on it.

I absolutely recommend the sampling menu, though you should stick with the 6 dishes (or less), which should provide enough variety at a manageable quantity. We had the 8 dishes option (only the 8 dish choice is 20% off on Tuesday) but it was way too much food, delicious though everything was. Unlimited pita (white and wholemeal) is included with the food. Here is a list of dishes we tried, all of which were at least good, with some being absolutely delicious;

Fatoush (Lebanese Salad)

Given how much meat will arrive by the end of this meal, I’d recommend this salad even if it was just chopped iceberg. Fortunately it’s delicious anyway; huge portion of diced tomatoes, shredded Romaine and sliced onions topped with an excellent middle-eastern (Sumac-based I think) dressing, along with pita croutons which soak all that olive oil up

Baba Ghanoush (eggplant dip)
A mild baba ghanoush that allows eggplant’s subtle flavour to come out, and doesn’t overdo the tahini or salt – not overbearing like the other dishes, so it’s great as a soothing / balancing mezze 

Jos Mahrouse (Lebanese spicy nut dip)
Spectacular flavour – I have no idea how they make this garlicky and spicy nut spread but it’s a must-try. Recommended as a house-speciality, I wasn’t too keen on the idea, but it ends up more like a hummus rather than a bunch of ground up nuts. Delicious.

Falafel (Chickpea patty)
Homemade falafel, if a bit too fried for my taste, works really well with the mystery orange sauce that accompanies it. I personally feel that falafel belongs in sandwiches with tahini and vegetables, and this style felt a bit heavy to me. Still a great example of falafel if you like it.

Kefta Kebab (minced lamb kebab with spices)

Lamb Kebab
I’m very hesitant about ordering kebabs because it’s like 50/50 that they come out rock hard and inedible. Have no fear though because the kefta and lamb kebabs were both juicy, soft and incredibly flavourful. Even people who generally don’t like lamb will gobble these up. I love kefta and they were delicious as expected, but the lamb kebabs really shone. 

Chicken Elmina (Pulled Chicken with mint, herbs and lemon) 
Interesting dish that I’ve never tried before – a bit sour for some of my friends, but the herbs give it a complexity that slays when you stuff it in some pita. I didn’t take a picture because frankly it doesn’t look very good. Give it a shot if you’ve tired of the standard kebabs.

Fousulieh with Lamb (Lamb and bean stew)

This was the dish of the night for me – I’m a sucker for bean and meat stews at their worst, but somehow they’ve infused the lamb with unbelievable flavour, which bleeds through into the whole stew. With the rice it’s phenomenal. A must-order.

Kibbe b’il Laban (Small minced Lamb balls with Yogurt)

The kibbe were tasty but since they were drowned in a sort of yogurt sauce, they lose the crunchiness of the normal mezze serving and then become just a heavy lamb meatball. Good not great. Would have preferred the sauce on the side as more of a dip?

We also had three types of Lebanese wine – all quite fruity and light (even the red) but appropriate for the food I think. About HKD 400/bottle and worth the price. There was no way we could finish it, but along with coffee/mint tea, they served a round of pretty good Baklava (though I'm not much of a dessert person so don't take my word for it)

Overall, I resist calling Zahrabel a great Lebanese restaurant because I’d hate for people to think of it so narrowly; it’s a great restaurant full-stop. Delicious, flavour-packed food without a lot of pomp and nonsense, great ambience and service, and some unusual recipes I’d never tried before. For the 6 dishes sharing menu it’ll run you about HKD 380++ per person for just the food, but recommend you try some wine as well. It's a bit more than middle-eastern food usually goes for in HK, but it's worth it. Definitely make some space in your date / celebration / business dinner calendar for Zahrabel.

A very popular dinner spot with easily the best Middle Eastern food in the city,this place also offers a great venue with fantastic value ideal for client lunches. It's quiet elegance and consistent taste and service makes it a go to venue for our client lunches. The ingredients are top shelf, taste is always authentic and spot on and the consistently friendly yet unintrusive service tick all the boxes.

If you are searching for a donner kebab style joint, save yourself the trip.  Zahrabel is the epitome of poshness from produce to presentation.  You can detect the care and precision employed from your entry to exit.  Smart menu with sharing mezzeh dishes, smart service, and a simple elegance to the place.   Staff will gladly educate you on its history namely that it is not a new restaurant per se but a continuing (Lebanese) family business.  The recipes have obviously stood the test of time which is a significant credit in a city like Hong Kong (or elsewhere really.)  Was I blown away by the taste though?  The answer is a resounding yes.  This place nails the simplest recipes like the humble humus but has other very interesting recipes and unique flavour combinations that will certainly lure you back.  Then there is the meat and just how they managed to  get the lamb to be so tender is anyone's guess.   Hands down the best lamb in Hong Kong.  It's an equal opportunities menu though - the veggie dishes were almost as outstanding as the lamb (a cauliflower dish was especially great).   6 courses, limitless bread, lebanese dessert,  coffee, lebanese tea and some pickled veggies will all amount to $420 per diner.  For its poshness, presentation and preparation, it deserves a 5 star rating all around.
題外話/補充資料: Perfect for evening dates or equally for large group occasions. Tip : be sure to request the corner window seat if you are on a date or prefer a spot of quiet as weekends are packed
