This is my worst restaurant experience in Vegas, and I'd give negative stars if I could.
The restaurant opens for lunch at 11am, but the "boss" doesn't get back from grocery till much later. As a result, the restaurant sometimes lacks even the most basic ingredients for their menu items such as tofu or curry powder. The waitstaff had offered to let us choose from the dinner menu (for which they had the necessary ingredient in stock) at lunch price, only to be denied by the boss upon his return.
If you are not particular about what to order, then this place may be for you; in fact, it looks to be quite popular with elderly Chinese folks. If you have a fine taste for Chinese food - or if you care about customer service - then stay away from this place. From what I understand, it's quite often for certain menu items - including their "specials" - to be unavailable. And this is inexcusable, considering there is a huge Chinese supermarket across street.
There are many other Chinese restaurants in Vegas; in fact, China Mama in the same plaza has an extensive menu, always accompanied by great customer service.
