The Main Tin has been a fixture in South Charleston for a lot of years. They have a very nice buffet that also offers sushi.
The buffet is good, but ordering take out or eating in and ordering from the menu is, obviously, better. I will say that their won ton soup is my favorite anywhere and their hot and sour soup is a close second. The won ton soup has the richest broth I've ever had.
The staff is friendly and attentive.
