Depending on what I'm in the mood for:
Chicken: used to be Popeye's, but they've done something horrible to the chicken. It now has that soaked-in-brine texture that KFC's has. So now when I want chicken, it's the stand-alone chicken shack down the street from my house. I do miss those Popeye's biscuits, though.
Pizza: Mama's, particularly the European Classic (pesto with enough garlic to stop a WASP in their tracks, mushrooms, sundried tomatoes, thin, thin, thin crust).
Burgers: Licks. Nothing better. Anywhere.
Indian: Since we're talking fast, I usually pick up some samosas from BJ's Supermarket around the corner (they have a bin of them in the front window - they're probably not as sanitary as they might be, but eh, they haven't killed me yet).
