Today is national “Pi Day,” which is celebrated annually on 3/14. The Greek letter π is the symbol used in mathematics to represent Pi, the ratio of the circumference of a circle to its diameter, which is approximately 3.14159, according to PiDay.org.

When we see the word Pi, we are not thinking about math. We get a mental picture of pizza pie!

So in honor of Pi Day, here are some of the best places to get pizza in Maine and New Hampshire:

Rosalie's Pizza in Bar Harbor, Maine.

Paras Pizza in Sanford, Maine.

Angelone's in Westbrook, Maine.

Tesoro Pizzeria & Restaurant in Bangor, Maine.

Micucci's Grocery Store in Portland, Maine. (My personal favorite.)
