More directly on topic, I don't eat at sit-down chains a whole lot. I'm usually either looking for something quick and cheap or something I'd struggle to make myself (e.g. non-Americanized ethnic food, which generally means non-chains).
But so far as it goes, I like Wendy's for fast food. For me, it hits a reasonable balance of cheapness and edibility. For fast casual, there's a small chain called Farm Burger that has a local restaurant. Think Five Guys with better food but without the bag full of fries. Jason's Deli isn't bad either. I've never been, but my sister swears by Moe's. For sit-down restaurants, Sonny's is kind of trash BBQ, but I'd still eat there before I moved to Alabama and had better options. IHOP and Waffle House are perfectly acceptable late-night spots. I have some friends who like Bonefish Grill. It's fine, I guess. And I'm far enough inland that I'm not overwhelmed with great seafood options.
