The bar for Asian food of any kind in Charlotte is mind numbingly low; almost all of it is awful.
Futo Buta is one of a very, very small number of restaurants in CLT serving decent Asian food. Compared to any good ramen place in more established metropolitan areas, Futo Buta could not be mentioned in the same breath; however, in Charlotte, this is clearly one of your best options. We had the pork belly buns (2 for $10) which were very good but tiny for the price. Tonkatsu ramen ($14) and Shoyu ramen ($12) were semi-flavorful and easily the best in town. It's not that Futo Buta is so great; it's just that the rest of what Charlotte has to offer is so bad. However, here's hoping the bar is being raised for what constitutes acceptable Asian cuisine.
If any Asian-inclined chefs are looking for a market with little competition, Charlotte is still wide, wide open.
