$10 for $20 Worth of Pizzas, Subs, and Salads at Ann Arbor Pizza & Subs

The pizza chefs at independently owned and operated Ann Arbor Pizza & Subs are often tasked with an unenviable job—quelling the appetite of a ravenous wolverine. They meet the challenge head-on, distracting the hunger-crazed invader with the University of Michigan’s signature maize and blue colors while they punch out hand-tossed, crispy, deep-dish, gluten-free and sourdough dough and simmer housemade marinara sauce. Many of the toppings that grace those pizzas also wedge their way onto the eatery’s 10 different types of hot sub sandwiches. If pies and subs don’t soothe the beast within, chefs can also prepare salvos of chicken wings and veggie-filled salads.
