I'm not 100% on the catfish... maybe because I'm not the biggest catfish fan, but the sides are absolutely amazing (except the store bought fries).
The first time I tried this place I got the lunch special w/sides ... I was so impressed with the black eyed peas that I went back and ordered more.
Seriously go here for the sides. The greens are amazing. When we bar-b-que at home we will go here and order a bunch of large sides to go with our dinner.
