Ignoring the Sonny Bryan's, Campisi's, etc., some of the ones that come to mind...
Celebration - I still go there occasionally but every time I do, it just reminds me of why I don't go more often. The food is just tired.
Mi Cocina - I used to live in the restaurant wasteland of Lake Highlands and this was one of the few choices. Overpriced and mediocre food.
Nonna - I know I'll get blistered on this but if I served you this same food in my home without you knowing where it came from, you'd be underwhelmed. I will say though the wines they have are fantastic.
Club Schmitz - I dearly love Texas beer joints but I don't get the attraction and popularity of this place.
