I would have to vote Wendy's as well. I'm bummed they got rid of the double stack, but it's still great. Nuggets, the Jr. Bacon, little fries and what not. You can get just about everything off the value menu.
Jack in the Box was also really great for awhile there....but they took off that Chili Burger and the "Big Cheeseburger" and put them on the regular menu. That sucks.
McDonald's? Man...I don't even really eat there anymore.
