I only go here once a year on New Year's Day. It's been an annual tradition for quite some time now. Bear in mind I am not the best judge of authentic Chinese food, but here are my thoughts.
The food itself is just OK. It seems a bit oilier than strictly necessary. There is a good variety of dishes in the dim sum service, though most things have shrimp, and I don't really like shrimp. Still, it's easy enough to pick out of most things. (And that is not their fault!)
The ladies who bring the carts of dim sum around are super nice and seem to want to feed you. It's really sweet. Sometimes it's hard to get something you want on a busy day, but they try to remember what you want and bring it around if they get it.
The surroundings are a bit out-of-date, but I don't find that to be much of an issue. It's comfortable enough.
Ultimately, I don't think I'd go here if I weren't meeting my friends for our annual outing.
