Love their dim sum, probably one of the best in AZ. We often come here once or twice a month @ weekend with my Asian crew, and a couple of risk-taking white tokens (^_^) The dim sum always meets our expectation. The only downer is the wait can get up to 30-45 minutes on Sundays, even though the food is usually fresher and you'll have more options.
If you've never had dim sum, my advice is to try EVERYTHING and do NOT (repeat, do NOT) ask what those are! They're yummy, I promise! ;)
