There are a number of ways to celebrate, from the Maryland Science Center to a pie festival in Mount Pleasant, but I’d suggest heading to the District of Pi pizzeria on F Street NW, which honors its namesake theorem with a slew of Pi Day deals. Buy any pizza and get a second for $3.14. Pints of the house beer, brewed by St. Louis’s award-winning Schlafly brewery, cost $3.14 all day. And at 6 p.m., the bar will have a Pi memorization contest: Anyone who can recite at least 50 digits of Pi wins a prize; the person who can remember the most takes home a $100 gift certificate.
