Capital City is in DC and it has a decent selection. I assume you like food too, in which case Good Stuff Eatery has AMAZING burgers. I don't care what people say about 5 Guys, it's a bunch of garbage, Good Stuff is the $hit, its right in the capital hill area, it's a must, i feel confident in saying you've wasted your entire life if you don't go there. It wouldn't hurt to take the metro and hit up Ben's chili bowl and get a half smoke with chili and cheese. Also sliders at J.Pauls in Georgetown
If you're into breweries/brewpubs, best thing for you to do would be to take the marc train 30 miles north to baltimore. Baltimore is a much better beer town, not to mention, it's way more fun. Go to fells point, canton, federal hill. A lot of bars have their own brew (green turtle, oliver's). Max's on Broadway has the best selection of beer in the city. Baltimore's more of a blue collar town whereas DC is much more white collar
Oh, don't go to Southeast DC btw, you might die. hell, just stay way from the whole eastern side.
