Pi Day is celebrated every year on March 14 in honor of the number pi, which starts with 3.14. Maybe math isn’t really your thing, but Pi Day should be, because a number of fast food chains and restaurants turn Pi Day into Pie Day, offering pie-themed deals (from pizza pies to dessert pies) in honor of the nerdy holiday. Here are the best Pi Day food deals for 2025, which are truly as sweet as pi(e).
7-11
In the spirit of Pi Day, 7-11 is offering entire pizza (pies) for the price of $3.14 in the flavor of your choice. And if you’re not a pizza person, don’t worry — you can still celebrate Pi Day without pie. In addition to pizza, 7-11 will serve quesadillas and a chicken tender box for the same festive price.
Burger King
If you’re looking for a sweeter take on the day, Burger King has got you covered. If you make a purchase of $3.14 or more, you can get yourself a free Hershey’s Sundae Pie. Just make sure you’re a Royal Perks Member in order to snap up this sweet treat.
Blaze Pizza
At Blaze Pizza, you can get an 11-inch pizza for $3.14 with a purchase of a regular-priced pizza. Plus, if you are dining in on Pi Day, you will get an additional buy one, get one for $3.14 that will be valid through the end of March.
BJ’s Restaurants and Brewhouse
BJ’s is offering another buy one, get one $3.14 deal for Pi Day: when you buy one of the signature Pizookie desserts (a skillet cookie that comes in flavors like cinnamon roll, strawberry shortcake, and triple chocolate), you can get a second one for the $3.14 price point. But this Pi Day deal can’t be delivered — it’s a dine-in exclusive deal.
Crust Pizza
If you grab one of Crust Pizza’s large pizzas on March 14, you can pick up an additional large pizza for the price of $3.14. But they will limit your Pi Day-priced pizza to just one topping, so choose wisely!

At select Grimaldi’s locations on Pi Day, you can get a fresh slice of pizza pie for $3.14. As long as you go in person, that is.
