If it did shutdown it is probably because they weren't doing so well.
If so, that is just baffling. I don't live in Tuscaloosa though, so not in tune with the restaurant scene dynamics. Both times I went there though, it was busy, though once was on a game day. But it was easily the best pizza I'd had in Tuscaloosa since Bama Bino was king of the scene in the 80's.
Mellow Mushroom is meh, but long established and recognizable. Plus a prime location. Pieology is trash. Nasty, nasty pizza. Never been to Heat.
