This is the best Dim Sum I've had in Vegas, I've been to Chang's three times in the last couple of months and it's been consistently very good. The service is just ok because every time we go we have to ask for our drinks twice. But really this place is about the Dim Sum which was great, there are always carts running around packed with food. The 'cart pushers' aren't very friendly or talkative but when you point to an item they give it to you so I'm not complaining. The prices are very reasonable for a family of four.
The place could use some more parking spaces because every time I've been there the lot has been full and I had to wait for somebody to leave.
