Pi Pizzeria, multiple locations in the St. Louis area: The St. Louis-area pizzeria specializing in cornmeal deep-dish and thin-crust pies makes good on its name and logo - the pi symbol - on the eponymous holiday. Past specials have included all-day happy hour; buy one pizza, get one for $3.14; free large pizza for anyone born on March 14; and pi memorization contests. pi-pizza.com
Peggy Jean's Pies, Columbia: The mother-daughter team behind Peggy Jean's Pies is always down to celebrate and have some fun, especially when it comes to their signature sweet. Since opening in 2014, the pie shop has celebrated Pi Day with festive specials and prizes like golden tickets for a free pie baked into its offerings, free T-shirts and discounting $3.14 off the selling price for all its pies. 573.447.7437, pjpies.com
Waldo Pizza, Lee's Summit and Kansas City: Sometimes the best way to celebrate a day devoted to pizza is in a cozy neighborhood joint surrounded by friends. Waldo Pizza has copious charm and plenty of pizza options, too - from make-your-own on hand-tossed, honey-wheat or St. Louis-style crusts to creative specialty pies made with locally sourced ingredients. waldopizza.net, waldopizzals.com
Sugarfire Pie, Olivette: It's not hard to treat yourself at the sweet sister of St. Louis-area barbecue favorite, Sugarfire Smoke House. Sugarfire Pie opened next door to the Olivette location in late 2014, serving off-the-wall indulgences like pecan-pie "pake" (pecan pie baked into chocolate cake), its signature brown sugar chess pie (also lovingly dubbed "crack pie") or stack pies made up of three pies baked and stacked atop one another. 314.736.6300, sugarfirepie.com
The Blue Owl, Kimmswick: If you want to go all out on Pi Day, head to The Blue Owl to get one of the state's tallest and most well-known pies. The Blue Owl's Levee High Caramel Apple Pecan Pie has been featured in numerous national publications, and for good reason: The 9-inch tall, 10-pound behemoth serves 10 and is filled with 18 Golden Delicious apples within its from-scratch crust. 636.464.3128, theblueowl.com
