I refuse to eat at Ruby Tuesday's... Their food is very rough around the edges. The locations are often old, located in old malls (especially in the midwest). Their only saving grace is their salad bar (and I'm generous there).
Bennigan's/Hooligan's (

) are not far behind the lameness of RT. Cracker Barrel really depends on your definition of Southern Food and wherther you like it or not...
Uno's, Chili's, crapplebee's, TGIF, etc are acceptable and generally in decent locations.
I've gotten to like California Pizza Kitchen, PF Chang's, Rock Bottom brewpubs, etc. I love Cheesecake Factory [Don't mind the calories...]
