Well, there's my school and several other places, but since this is major chains only, the Burger King closest to me (I don't know if it's all of the BK's here, since I only go to that one) doesn't take AMEX, even though all the BK stuff has AMEX listed as a payment option. There's even a huge "Pay Your Way" (or something like that) window sticker that lists MC/Visa/AMEX and I'm guessing a BK gift card as payment options.
