The Cookie Counter
In honor of Pi Day, the vegan ice creamery and bakery will bake up pint-sized pies in apple, cherry, and oatmeal pear and serve a pie milkshake made with real pie (!).

Dexter Brewhouse
For Pi Day, Mollusk Brewing will release their "bizarre and distinct" farmhouse bier inspired by pi(e)s of the pizza persuasion, "brewed with tomatoes, garlic and oregano" and "reminiscent of Totino’s frozen pizza with a rustic Saison-like bite." Dexter Brewhouse will provide pizza-inspired dishes to complement it.
