I made a reservation for dim sum and after arriving there, there were like 20 people in the waiting area, I still had to wait like 10 mins. Even the waiting time was not so long and the waiting area was bigger than many Chinese restaurants, it was still uncomfortable to be among many aggressive older/middle age people trying to get tables.
Inside the restaurant, it was pretty spacious. It took us a long time to get the attention of the waitress/waiter to take our orders. I think they were just too busy. The food was average, but it really depends on what you order. If you order the standard items, they rarely go wrong anywhere.
If you go after 1pm in the weekend, I think there is no line up. If I ever go there again, I would pick a time with no line up.
