Quizno's Subs on State Street really is a great place to stop in for a quick and delicious lunch. They run excellent specials and even their regularly priced subs are fairly reasonable for what you get.
They are fairly fast, getting you in and out with your lunch in ample time to enjoy it over your lunch hour. The employees are generally pleasant and I've yet to run into one that isn't smiling and friendly.
Based a lot on the same technique and styles as Subway Subs, they offer freshly made subs to your specifications. While the soups are nothing exceptional, the salads are very fresh and again, made to your specs. Add a little sweet treat to your meal for just a little bit more. My favorite is the triple chocolate brownies!
