This is the cleanest (fast) food restaurant I've been in a long time (it even smells clean)! The service is impeccable and very friendly. If you need a break for the noise, they have a nice covered patio out back.
Quizno's food quality is top notch, especially when you compare it to McSub(way). The ingredients are actually flavorful and the bread is top notch (especially when you compare it to the spongy stuff the other shops are feeding you).
Save room for the soups, if you can. The clam chowder has lot of clams and potatoes in it, and taste like sometihng that you would eat in a fancy restaurant, or that your mother would make. My wife has tried the chicken noodle and the chili is pretty good.
In addition to the regular fountain drinks, Quizno's has a added tropical tea and fresh pink lemonade, both very good. Enjoy!
