From Denver to Dublin, these sub specialists have been serving up their toasted torpedoes to a growing army of fans. Founded in the Colorado capital in 1981, Quiznos is now the fastest growing quick service restaurant in the world, with outlets in 21 countries. Five city centre locations, and a few more in the suburbs, serve wraps, soups, sandwiches, salads, gourmet coffees, breakfast, and subs that are toasted with ingredients to seal in and enhance the flavour. A great spot to pick up some healthy and filling food on the go.
