About the only place I still go to these days is called Eazie, which is some kind of noodle/rice thing. Not sure if it really qualifies as a fast food restaurant though. They get your food fast and it isn't that expensive, but the food is actually prepared on the spot out of mostly the raw, fresh ingredients and it does taste like it is of decent quality (way better than what they serve at McDonalds and KFC at least).
Other than that, I think Subway is okay but perhaps a little too expensive for what you get. The good sandwiches cost around 8 bucks here, which I think is a bit much for "just a sandwich that I'm having for lunch". Hence why I seldom go there.
