I'll be honest; I've never been there for dim sum however I've been here a few times for dinner with my family. Yes they are expensive however it is worth every penny in my opinion.
Last time I went there was for my birthday dinner. There were about 5 adults and 2 kids (under the age of 6). When we first walked in we were greeted and had a table within 10 minutes. They were nice enough to give us a spot right by their HUGE fish tanks so the children could be entertained throughout dinner.
We ordered right away. Sorry I don't remember the proper names of the dishes so bare with me. We had a wonderful plate of SHRIMP just blanched in water with a nice spicy soya sauce for dipping. The shrimp were fresh and when you dip it into the sauce it makes the shrimps sweetness stand out.
Next dish was the Peking Duck. They slice the duck right in front of your table which helps build the suspense of tasting and eating it since you can see the wonderful juices dripping off the duck. It was amazing. Their Lettuce Wrapped with Diced Duck Meat was pretty good as well, nothing super special about it but it was executed well.
Now if you come here for DINNER, you MUST try their BBQ PORK and SIRLOIN STEAK. They are beyond amazing. The steak is melt in your mouth delicious and their BBQ Pork is so good that you will not be able to forget it.
Afterwards you get your typical Chinese desserts and they are done well. Their service was great. Never had to wait too long for anything, none of our orders were missing either. Overall, it's a great place to go for dinner. The kids LOVE their huge fish tanks with lobsters and crabs the size of a baby. =)
