I walk in the Yat Tung Heen yesterday, the manager told me cannot walk in to enjoy Lunch even on weekday, It must book before at least 1 week.
Wow, It is Wednesday yesterday, It cannot walk in to have lunch just by one person. I apply leave to specially to try this Chinese Restaurant. The manager told me to book a table at least One week before to have lunch. It is the cheapest price on weekday, that is Monday to Friday.
I may try next time by book an a table one week before.
