I'll make it short and to the point... I'd give this about 2.5 stars but to be nice I'll round it up and here's why:
The service was good and everyone from the host to the bus boy as well as waiters were nice.
The food:
fried green tomatoes: tasteless, and the piece of pork belly on top was chewy on the inside, crusty on the outside... Not good at all.
The cornbread: extremely salty and the crust tasted like rust possibly from the small iron skillet it was served in.
Chicken biscuit: again the biscuits were salty and stale and the chicken was rubbery and over-cooked.
Mac'n cheese: nothing special at all, very neutral and bland in flavor.
I'm not sure how these guys averaged 4 but I wouldn't be surprise if the reviews are from insiders.
