Jose Andres Jaleo, great Spanish food.

International food: You name it. You should be able to find food from practically any country in the area, just with a quick Google search. Then pick whatever has the best location/reviews.

A few of my favorites are Bistro Aracosia for Afghan and The Grill from Ipanema for Brazilian

DC itself isn't known for any particular cuisine. A lot of cities aren't.

When we visited in a June, we had terrific seafood at Pearl aDive Oyster Bar, superb French cuisine at Le Diplomate, tapas at Jaleo and a wonderful small plate experience at Gypsy Kitchen.

DC is somewhat known for its thriving Ethiopian restaurant community. You might like to try Zenebech, Ethiopic, Gorsha, and others.

I'd look at Old Ebbitt Grill near the White House, the oldest tavern in DC and a varied food menu, Ben's Chili Bowl for the most iconic/well known cheap eats (though I've heard rumors it may close?), and Eastern Market including Market Lunch for more budget friendly options, but good ones can be found all over the city.  You could consider lunch instead of dinner to save a few bucks at the expensive places.

“ I'd look at Old Ebbitt Grill near the White House, the oldest tavern in DC and a varied food menu,”

Good food. The “ oldest tavern” thing is a bit misleading because the current premises only date from 1983. Other than some stuffed animal heads over the bar, there’s nothing remaining from the other locations used by the restaurant over the years.

Potential closing of Ben’s Chili Bowl? I’m not a fan of the place. But a closing would be huge news in DC. Where did you hear that?

It's also misleading to think of the Old Ebbitt as a "tavern." By annual dollar sales volume, it's one of the top three restaurants in the US. That said, I like it a lot.

The Ben's in Arlington closed as a result of the pandemic. To the best of my knowledge, the original location is still going strong.
