This past trip, we tried Hash House A Go Go, Millers Ale House, Margaritaville, Bubbalou's Bodacious Barbecue, and Carrabba's all for the first time. Great experiences at each, and we would recommend them all. You can check out my May 2015 trip report currently in progress (see the link in my signature) if you want to read my full reviews with photos.
Others we have done in the past and enjoyed.....Chili's, TGI Friday's, Giordano's, Buffalo Wild Wing, Cracker Barrel, Golden Corral, Steak & Shake, Olive Garden and Friendly's. Yes, most are chains but we have none of them around here. Consistently good food at all of them, though the atmosphere of Golden Corral can sometimes leave something to be desired. Giordano's is a must-do if you like deep dish pizza!
