Fast food is unhealthy, but what is your favorite place to eat?

For hamburgers, I'd go with Carl's Jr. They seem to be the least nausiating, and have the most food for your dollar. For ethnic (if it can really be called that, it's so Americanized), I'd go for Panda Express or Del Taco. Del Taco, yeah, I know. But their chicken soft tacos are actually pretty cheap yet good.
