Hot dogs and soft pretzels are great, but the next time you’re going to Nats Park, stop by Rasa in the Navy Yard beforehand for dinner instead. This new Indian fast-casual spot makes everything, from the samosas to the chutneys, in-house - and the space itself is way nicer than most places following the build-your-own-bowl model, with swinging chairs and wooden light fixtures you’ll want in your apartment. Nothing on the menu is more than $13, and if you don’t know where to start, the Home Cooking bowl with turmeric ginger shrimp and the Tikka Chance on Me are two options that will keep you full for the next nine innings.
