I've been in the US for 2 years now, and I did my best to try as much fast food as possible without destroying my health.
I didnt like: Sonic, Arby's( curly fries are good doe), Subway (meatball sub), Taco Bueno, Taco Bell, Wendy's, Burger King (Whooper house in Orlando was ok, for some reason), Ceasars(Pizza), Jack in the box.
Average: Chipotle, Shake Shack, Five Guys, Fuzzy's, Schosloschky( no idea how to spell it), Domino's, Pizza hut, Rising Cane's, whattaburger, KFC, Dairy Queen.
Good: Chick-fil-A, Torchy's, Panda, Hardee's, Papa John, Qdoba, in and out, wing stop(hate their fries), Braums, Marco's Pizza.
I can't remember some of them, it means I'll have to go again.
