I'm a sheltered guy and vacation is this week. Figured I

Make sure you get to the Air and Space Museum. Nothjing like it anywhere.

Sounds like a good plan, OP. Plenty to do. Good eats. Read washingtonian magazine or the smithsonian website to see if there are any traveling exhibits that interest you at various sights, just in case you didn't know! I always find the best treasures that way, something odd and usual that way, as well as restaurant rankings on washington post.

Smithsonians are free. My favorite is natural history too, the gems specifically. One of the museums will have a night event for afterhours, but only one! The top two non-free non-smithsonian museums are Spy and Newseum. My favorite air and space Udvar, is out by dulles airport and more difficult without a vehicle or reason to be so far west. It's worth it, however. Enola Gay is there and you can get inside a control tower simulation with live traffic and images from the airport.
It. Is. Hot. right now to be in DC, and you'll notice the blocks are long...you will want to wake early for any walking/exploring and then get into the A/C inside a museum, in my opinion. The bar and live music scene at the Clarendon metro might be safest evening for ya. Where did you pick to stay? That might determine where you should hunt for bars. There's a famous rooftop one that is now top of the W hotel, which gives you a view right into the White House grounds and windows. Sequoia in Georgetown has a pretty potomac sunset view. Vietnamese food in northern virginia (various and of course pho choices) and some of the best steaks in the US and burgers (fave:Ray's hellburger), are probably the best foodie choices distinctive for the city. I love going in Dean and Deluca, almost all cupcake places, and there are a ton of hipster big politico kind of bars with bartenders slinging the classics, esp close to the white house.
