wendy's ftw! i love their bacon sandwiches =P go baconator!
BK and Mc are the nly ones here in Arg, so I'll go with BK. It's so damn better than McDonald's, has a bigger varity of Burgers and Desserts imo.
Five guys burgers and fries FTW. Best cheeseburgers and fries ever! Also, you get free peanuts! :D
