I've been transplanted from SoCal to Northern Va., which is almost completely bereft of eateries except for Wendy's, Pho, and Chinese Buffets. Also there is nothing open late except for IHOP and Denny's, and the restaurants here allow SMOKING! Yecch!

I would die for any of the following:

Carl's Jr.
Claim Jumper
Elephant Bar
El Pollo Loco
Jack In The Box
In & Out Burger
Mimi's Cafe (owned by Bob Evans, would you please tear down all the Bob Evanses and put up Mimi's Cafes?)
Sonic
Waffle House
