CINCINNATI -- 3.14159.
It's the ratio of the circumference of a circle to its diameter, a mathematical constant known as Pi. That's why March 14 is commonly celebrated as Pi Day.
Since we don't go around with measuring tapes, Pi Day is often translated into "Pie" Day. After all, they're round, too!
In honor of Pie Day, here are nine of our favorite places to get pie (both sweet and savory!) in Greater Cincinnati.
O Pie O is the only dedicated pie bakery on our list. Whether you want sweet or savory, O Pie O has you covered. Chicken pot pie, quiches, pocket pies and empanadas cover the savory side, and sweet pies range from the bakery's famous honey vinegar pie to apple with rosemary caramel to sweet potato, bourbon pecan and Meyer lemon. If you eat in, it has a full bar featuring cocktails and local beers. 1527 Madison Road, East Walnut Hills.
Need pie for one? Head to Coffee Emporium, where there are individual pies made fresh in Coffee Emporium's own bakery. They're just enough for one hungry person to eat or for friends to split over coffee. Apple and lemon meringue are regular fixtures. 110 E. Central Parkway, Over-the-Rhine; 3316 Erie Ave., Hyde Park.
Although the spot is better known for its croissants, Frieda's tarts and pies are baked with old-world care and worth checking out. Frieda's takes orders and has a variety of pies and beautiful fruit tarts available daily. Get there early, though. They sell out quickly! 6927 Miami Ave., Madeira.
Not only does Cake Rack Bakery have a variety of pies regularly for sale and custom order, you can take pie-making classes there, too! The next class, which has seats still available, is May 2. For $95, you can learn how to create crust and fillings from custard to apple caramel to chicken pot pie. 113 W. Elder St., Over-the-Rhine.
This quaint cafe has a variety of sweet pies to enjoy year-round. Usual selections include apple crumb-top, triple berry, coconut cream and a variety of rotating fruit and cream pies. Enjoy whole pies or slices, and either take them home or savor after a sandwich in Bluebird's cafe. 29 Village Square, Glendale.
Available at lunch Tuesday through Friday and during brunch on weekends, the variety of quiche at Pleasantry is ever-changing but always creative and delicious. Past quiches include country ham and cheese and all can be paired with Pleasantry's excellent coffee and wines (as expected for a restaurant co-owned by Joanna Kirkendall and Daniel Souder of 1215 Wine Bar & Coffee Lab). 118 W. 15th St., Over-the-Rhine.
This small bakery uses scratch recipes to make pies that remind you of the ones your grandma made. Order pies for pick-up, including apple brown sugar butter crumb, double-crust apple pie, blueberry lattice, pecan, double pecan and mini apple and pecan pies.
This bakery, named after the tiny ceramic statues shaped like birds put into pies to release steam, is currently found at Folk School Coffee Parlor, featuring savory pot pies, applesauce pies and chocolate chess pie. Once farmers market season starts, you can find Piebird at several markets across Northern Kentucky. Folk School Coffee Parlor, 332 Elm St., Ludlow, Kentucky.
Although it doesn't serve traditional pie, it's hard for us not to include a pizzeria that is named "Pi." Its thin, cracker-style crust and deep-dish pizzas are both classics, including Cincinnati-specific Chili Pi-Way (its take on Cincinnati chili with Skyline, goetta and onions) and more traditional options such as the Delmar, a barbecue chicken pizza. However, it also does have an apple pie with cornmeal crust and a crumb topping. It'll be offering Pi Day specials, too. 199 E. Sixth St., Downtown.
