Went for the first time a couple days ago. My aunt lives in Vegas and recommended the place. Overall the place was good, not the best dim sum ever, but pretty good. Took a party of 7; half had never eaten this type of Chinese food, but they really liked it.
A couple really good things; 1) they serve dim sum all day not just morning/lunch time; you can get chow mein off the cart in individual sizes vs. having to order a huge plate.
Cart service was pretty quick and came by often, wait service was slow.
Paid $71 plus tip for 7 people.
When in Vegas again, I would definitely go back.
