There was one day last month, when I was intending to make my way to the Robuchon cafe when I noticed, hey! There's an eatery in place of 360, and it looks like they're finally open! Upon closer inspection, my colleague and I realised that this was in fact their internal trial/tasting session and that they weren't due to open for a few days yet.
We cheekily joked with the managers, hey so do you need some help with tasting? And guess what, they were nice enough to provide us with samples of almost every delicious thing they had on offer. We didn't even need to eat lunch after, with all the delicious food. With that gesture of good will, they secured my loyalty - it is heartening to see a restaurant that is so proud of its food and cares about its customers that the managers will not only invite you to join their internal tasting, but chat with you about the business after. For as long as my office is within 10 minute proximity, this will be my go to takeout place. I've been going twice a week or more since its opened.
To secure loyalty of course, taste is also a very important factor. No problems there. The offerings are quite similar to Simply Life (and indeed, both are owned by Maxim's), but on the yumminess scale this blows Simply Life out of the water entirely. They have a good selection of "solid" salads (i.e. not leafy), as well as a nice Caesar salad. Try the roasted eggplant with miso, or the cauliflower salad with an interesting smoky/cheesy flavour. In terms of sandwiches, their roast beef sandwich is excellent. The beef is not the thick chunky variety a la Westwood Carvery, but it's lovely in its own way with mustard dressing and a generous helping of bacon. Ham and cheese croissandwich, with it's soft melty brie, is on par with my other favourite sandwich at Robuchon cafe. Soups are good too, although the selections don't change as often. Perhaps the biggest crowd pleaser here though is the Borough Market duck confit sandwich, which has improved upon the London original as it this version is more moist. Have not tried the hot food yet, but it looks good.
The seating area has a very chill vibe, a nice place to get away for a little while, even though it gets crowded at lunch and everyone next to you probably needs relaxation as much as you do. The silver plastic cutlery that supersupergirl mentioned in her post below is also a nice touch - shows that they really thought about how to improve the dining experience for people.
Pricing is really quite reasonable. $45 for a sandwich, $30 for a coffee, $15-20 for a pastry, $55 for a small salad, $75 for a main course and some sides, from what i can remember.
One small thing to improve upon is perhaps efficiency - understandably, they have just opened and staff are still getting warmed up to the system. Also, currently there are separate lines for sandwiches, salads, hot food and coffee, and then another line for the cashier. So if you want 3 items, you might end up queuing 4 times. I don't know if a single line approach would improve the situation (or if it would even be viable, given the long curved counter layout), so perhaps the only thing to do is to improve staff efficiency and maybe merger some of the lines.
