Where should I go out to eat after?
The protest concludes near Pennsylvania and Fourth Street NW -- the closest metro stop being Archives-Navy Memorial a few blocks away. If you feel like beating the rush by grabbing a bite to eat first, there are a more than a few options.
Blowing off steam at Penn Social is one way to wind down the day, or get the night started. Located only a short walk away, they have bar games, a well-stocked bar, and happy hour food options. If you think that might get too packed because of proximity, two similar options would be District ChopHouse & Brewery on Seventh Street NW or City Tap House Penn Quarter on Ninth, which offers a wider variety of food options than Penn Social.
If you feel like treating yourself to a more traditional sit-down meal, Seventh Street NW is full of great options. Oyamel by Jose Andres serves delicious and authentic Mexican food and made-on-the-spot guacamole, or head to Rasika for some of the best Indian food in the city.
