My rating is more like '3.5' than 3. Its a tough to decide my exact rating given this place does provide authentic Cantonese style cooking and the prices are reasonable. But on the down side, the decor/ambience is nothing special.
I have been here a few times with my in-laws, who tend to find one place they like and stick to it. For years. No diversion, no change, it will not go well, we simply cannot dine at other restaurants or run the risk of family argument.
Moving on, I've had Dim Sum here quite a few times for lunch. I don't do the ordering, my in-laws speak fluent Cantonese. The menu is in Cantonese. But don't worry, if you don't speak Cantonese, just look at the food passing by you on a cart. If you like, motion the server you want some. They will serve the dish and mark your menu for you.
Although the clientele is by majority Chinese, there are a few non-Chinese (like myself!) in the crowd. So you will not feel out of place either way. This is a massive restaurant, more akin to a Banquet hall that they open up for regular dining hours during the day.
The washrooms...ah unfortunately typical cleanliness I've come to expect with Chinese restaurants (having travelled to China, it can be worse, a lot worse. But if we want to compare which country has the worst washroom, far and away my winner would be India! Still traumatized by that gas station hole in the floor outhouse never been cleaned for at least 40-50 years.)
Getting back to this place, the washrooms are ok, relatively clean. Just sometimes they don't have paper towel. Or soap. Or its a bit messy.
You will need reservation for busy times, so lunch time or dinner time. It can get really packed. You can still get in without reserving, but might wait a few minutes.
Lets talk about the food itself, it is pretty good! Definitely authentic and this is not your typical Americanized Chinese take out food. Dim Sum is traditional Cantonese brunch, with wide range of fried, steamed and otherwise cooked foods. Most common items are dumplings (shrimp is my fav!), buns, flavoured rice, and some desserts. Watch out for the chicken legs!
For dinner they have family style Cantonese meal. The quality of the food is good! Usually there is a total price for a selection of dinner items to be shared. For example, package can include lobster, fish, duck, chicken two kinds, veggies and some kind of mixed vegetable and meat dish. The price is reasonable, averaging $15-20/pp often with a little leftover to take home.
