I think out of all of those listed, I'd have to say it's a tie between Domino's Pizza and Subway. I don't really eat Subway that much, but I think their sandwiches are quite nice. Domino's is really good too, even if I don't have it that often either.
my fav is Chick-fil-A I eat there and chipotle a lot,like 5 times a week at Chick-fil-A lol i sometimes wonder if ill turn into a chicken haha and Starbucks does sell food like sandwiches and little coffee cakes,although all I ever get is drinks .
I had no idea Panera was considered fast food. The more you know.
I've heard of all of them, but I don't have most of these around me.
My favorites are Five Guys and Moe's, too bad they aren't on here. I'll go with Dunkin Donuts.
