Where is a good Chinese buffet restaurant

There's not one in river city. Panda Express is the closest you'll get

Sushi Wok is right down the road in the strip mall at Main St and Airport Center Dr. Just a 5 minute drive from River City Marketplace. They have great food and you get good portions for your money. I personally love the pork fried rice. I get a large for about $8 for dinner and then have plenty left over for lunch the next day.

Wasabi

I agree with William. Have only seen Panda Express.
