Around here, my favorite burger fast casual / carryout joint is Five Guys -- about 1,000 US locations. Very similar to In-N-Out Burger, but the burgers are slightly larger and cost a bit more. Only problem: by the time I get home, the fries usually end up soggy. McAllister's is very good for soups and deli sandwiches. Chick-Fil-A beats the heck out of super-salty KFC.
