When it comes to March 14, you can definitely have your pi — or pie — and eat it, too. The annual Pi Day, which celebrates the symbol for the ratio of the circumference of a circle to its diameter, is a great excuse to show off your inner math nerd and eat slices of pie shamelessly. You don’t need to be irrational and limit yourself to math competitions, either. The Chicagoland area offers plenty of ways to celebrate all things that come in a circle. To get started, check out the following ways to celebrate on 3/14.



Bang Bang! Pie Shop
2051 N. California Ave.
Chicago, IL 60647
(773) 276-8888

This pie shop features a rotating array of seasonal pies, and typically features a fruit, a cream and a chocolate pie every day. Previous flavors have included lemon cream, coconut cream and Shaker blood orange pies. To preorder a pie, call Bang Bang! If you don’t have a sweet tooth, you can still have pie; Bang Bang! offers a rotating menu of savory pies, including chicken pot pie. It’s not all pies at Bang Bang! either. The pie shop sells biscuits and has a topping bar complete with whipped butter, herb butter and a variety of jams. In addition, the shop has a sweet deal for March 14 and will sell five different pies for $3.14 per slice.

For many Chicagoans, deciding where to get pizza can be a contentious debate. Do you stick with deep dish or do you venture into thin-crust territory? But if you just want a pizza pie, consider heading to Lou Malnati’s Pizzeria. Established in 1971 in Lincolnwood, Lou’s specialty is its deep-dish pizza loaded with cheese and sauce. Don’t forget to go all out on Pi Day and include pepperoni on your pizza. Thin-crust pizza is also available, and no meal at Lou’s is complete without its salad and signature creamy lemon garlic dressing.



Central Continental Bakery
101 S. Main St.
Mt. Prospect, IL 60056
(847) 870-9500

What’s a Pi Day celebration without pie? At Central Continental Bakery, a mainstay of Mount Prospect for more than 90 years, you can choose from a variety of pies, including cherry, blueberry and peach. Specialty pies are also available for sale, including lemon chiffon, French silk and Mississippi mud, but must be ordered in advance. Pies are available in six and nine inches, making it the perfect size for sharing — or at least ensuring you have leftovers.
