Excellent thread idea. And for extra brownie points, hours of operation would be fantastic. A lot of people are up pretty late, so it would be good to know what's available in the wee hours.
Alas, I have no recommendations to give. I'm terrible at searching out new places in my car, and I have yet to venture anywhere by that local Wendy's for food.
But Windows Live Local points to
quite a few near-by eateries. Looks like there's a Qdoba, Golden Corral, Il Fornaio, Chipotle, Taco Bell, McDonald's, Country Kitchen, Rumbi Island Grill, Wahoo Fish Taco, Panera Bread, Illegal Pete's, Red Robin, Quiznos, Subway, Tokyo Joe's, Domino's, and Wendy's (and a good 50 other restaurants) in a one-mile radius. It's amazing how dense the restaurants are in that area (and how dense I must be to miss them all).
I think I'll print these things out and get a little variety at the con.

(Sorry for not posting specifics on these places. Give me a little time and I'll put together something more useful than a list of names.)
