That's a tough one!
When I read your question, I was prepared to shout out "Mama Melrose's" right away, but reading the posts from others makes me realize how tough a choice it is. I can't decide on a favorite, but IMHO, here are the positives:
Mama Melrose's: Out of the way and therefore less "hectic" than others. The kind of atmosphere you'd expect from a nice, but casual Italian restaurant. The spicy Italian sausage with pasta, peppers and onions is awesome!
Sci-Fi: The unique atmosphere of the drive-in setting is great! They do have "non-car" tables, too, if anyone in your party uses a wheelchair and can't transfer out of it to the little car tables.
50's PTC: The unique interactions with your "family member" waitperson (ours was Uncle Wex) is awesome, but only if you want to play along. Know that they will "nag" you if you put your elbows on the table (which I got busted for several times) or other rude table habits, but I think it's fun. Food is the kind that heart attacks are made of, but at least you'll go out with a smile on your face - the fried chicken is some of the best I've ever had.
Brown Derby: We usually save this one for dinner, although it would certainly be cheaper at lunch. Very classy place, with all those caricatures all over the walls... even in the bathroom! Service has always been great here, as has the food.
Tough decision - just try them all!
