I was there in 2012.
I went off in search of a vegetarian place and it ended up being closed. It was in a complex that I think was the Chinese Cultural Center but there were tons of people across the hallway trying to get into a place with large tables. There was a man who kept trying to put up a sign that said "closed" to try to discourage more people from walking in but it wasn't working. My husband and I were the only non-Asians in there. People really were enjoying what they were eating and we had to work to convince our server that we wanted strictly vegetarian food. In the end, we had an amazing meal. Almost all tables were for large families but there were a few smaller tables. Lots of drama and celebrations and families did have their kids there.
I believe that this is where it was. It helps to have a car because we had to get taxi service and in the later evening, there weren't so many cars on the road so you couldn't hail a cab or anything.
For higher end, we enjoyed Alan Wong's restaurant.
Have a wonderful time!
