I had the chance to try this place out on one of my first trips to Vegas several years back. I remember it being my first trip to the Gold Coast casino.
It appeared tucked away near a little food court, and the long waiting line made it recognizable. I went with the standard dim sum fare available, soup was great, chicken wings were a little rubbery and way too greasy. A few pushy people outside, as some other reviewers have mentioned.
I'd definitely go back, just haven't been on that side of town in recent Vegas trips. I remember regretting not going back the next day, as the little snack bar beside it was terrible.
