This is Las Vegas. So I have to tone down my perception of food quality in general. And I've been to this restaurant 3 times in the past 24 months, at different time.
It served Dim Sum all day. But as expected, the dim sums after the rush hour, i.e. at night, was awful. During lunch hours when the foods were fresh, and abundant. The variety has been standard. Nothing too surprising. Lots of fried foods for American.
The price, as in all Las Vegas, was higher for what it's worth. For 2 people the last time we ate there, it's $30 for 10 items. Egg tarts are medium price (all places I've been to charged low price). The chow mien was a bit bland. The Chinese broccoli with oyster sauce was very tender on the stalk.
So diners, it's good to have dim sum here during busy hour. For tourists, it's Las Vegas. Get used to it.
