Five Guys has the best burgers and fries - a bit pricey, but you can customize any way you want and get a ridiculous amount of fries. I sometimes toss mine in old bay seasoning at home, or I just get them with the cajun seasoning. It's bomb.
Chick-Fil-A has the best chicken sandwich. Their nuggets are also really good and make for great snacks if you get the catering trays.
Jersey Mike's is easily the best sub chain in America. They have the best bread, the best meats, the best cheesesteaks, and they're from Jersey. I lived off of Jersey Mike's while at college. The best thing to get is the chipotle cheesesteak.
Wawa is the undisputed convenience king. They have the best deli station of the bunch and revolutionized the game. Hoagiefest is undefeated. A nice meatball parm after a night at the club always hits different.
