According to the Nats Park information guide, you can’t bring a whole pizza into the stadium. Luckily, All Purpose opened right on the riverfront, so you can still get your pizza fix without having any issues with security. It’s a great spot to sit on the big patio overlooking the water, have a beer, and split a few pies and appetizers before a game. The Buona with hot honey and the Curveball with barbecue chicken are two of our favorites, but there really isn’t a wrong order at this place.
