This is a review about the one on Rainbow and Flamingo. I cannot speak to the others.
I am married into an Asian family and we mostly eat Asian food so I have been in Asian eateries high and low in many cities. This is one to avoid.
I was joking with my sons the management must pay kids to pick up the dead shellfish that wash ashore with the morning tide and this is what they deep fry to cover up the spoiled taste which did not get past us. Most people go for the "all you can eat crab" but it was more like "all you can keep down." The rest of the offerings were OK but pretty standard low-end offerings heavy on the fried side. Frankly, several of us felt ill the rest of the evening. Never again.
