I’m not gonna lie — math wasn’t my strongest suit in high school, especially once I advanced to calculus. Limits, functions, derivatives and (shudder) integrals? Hard pass. 

Now Pi, though… who doesn’t love the ratio of a circle’s circumference to its diameter? Plus, the holiday for that irrational number is the perfect time to snag deals on circular foods like pizzas and pies. (Pie donuts?)

Whether you’re celebrating the mathematical constant 3.14159265 (and so on) or simply want to take advantage of a delicious slice, check out the restaurants offering discounted food on Pi Day, March 14.
