&pizza will transform to a wedding chapel on Pi Day

Federal Hill’s &pizza will again transform into a Las Vegas-style wedding chapel, hosting weddings for couples on March 14 — also known as Pi Day.

It’s a tradition the Washington, D.C.-based chain has held since 2015, when a couple got married beneath one of the pizzeria’s ampersands. This year the chain plans to host at least a dozen weddings between its D.C., Baltimore, New York and Philadelphia locations.

Couples participating in the cheesy celebrations were selected by &pizza after applying in advance. The weddings — complete with a ceremony, flowers, photography and plenty of pizza — are free to the couples. Pi, for those who need a geometry refresher, is the ratio of a circle’s radius to its diameter. It’s a mathematical constant rounded to 3.14, so, naturally, Pi Day falls on March 14. It’s a “holiday” often celebrated by pizzerias and pie purveyors alike.

Despite the weddings, &pizza’s shops remain open to the public throughout the day.

The Baltimore location, which opened in 2016, offered weddings for the first time last year, and at least one Baltimore couple held their wedding at the Federal Hill shop.

Pi Day weddings aren’t the only stunt &pizza has hosted. The shop has also offered tattoos of its ampersand logo to guests, who in exchange received free pizza for a year.
