I'm no math nerd, but $3.14 pizza on Pi Day? Yes please.
Despite the 1.5 hour wait in the freezing cold (a LOT of people like cheap pizza), I enjoyed my first experience at Pi Co. Once I got inside the actual restaurant, the line moved relatively quickly and I had my pizza box in hand in less than ten minutes. They have a good variety of toppings, and even though they recommend only 4-5, you do you boo! Go ham!
For the sake of comparison, I will say that I like Blaze Pizza more - I prefer their thin crust and the fact that they have "finishes" like pesto drizzle and arugula. But since I work in the Yorkville area now, I'm perfectly happy coming to Pi Co instead for my custom 'za fix.
