Watch out for Taco Bell, e.coli has been linked to them out east. Culvers, for a chain, has awesome burgers!
Seeing Taco Bell in the list reminded me of one place I forgot to mention... Baja Fresh. Absolutely the best Mexican food around that's quick and cheap.
I've had Culver's when I when to Austin, Texas and their ButterBurger Deluxe is to die for! Starbucks is another favourite, as is KFC. Anyone heard of Whataburger? Their burgers are pretty good too.
I work at Arby's so thats our of the picture. Burger king all teh way with chicken tencrisp thing and chicken fries. Prolly Wendy's for fries. And jack in teh box cause of teh burgers are sometimes good.
