Dim sum is not bad for Vegas. I brought my mom here because I needed someone who could order for me; but we are too spoiled by San Francisco Bay area dim sum.
Some of the dishes I tried had a bit too much gristle in them. My litmus test is often the quality of the egg custard (looks like a mini pie). This place was decent.
Service was slower than what you would find in the bigger cities. One cart lady in particular seemed extra grumpy.
I think I'll be sticking with Cheng's or KJ kitchen if I need a fix. Those places seem to be busier, so the dim sum is often fresher.
