A pretty good espresso bar to seek out if you're in DC. Fitout is OK, but a little on the cold side, doesn't help being under an office building. Coffee is good, you won't fault it, and the staff are knowledgeable but not overly engaging - granted it was late on a Friday afternoon. No wifi - which is always a positive in the States .... stops people camping out for hours on end.
This is the second outpost for the Filter Coffee Empire and if this is how it's going to grow, I say let a dozen more locations blossom. The Foggy Bottom store shares the same attention to detail as their first shop: sterling service, fine roasted beans (courtesy of the masterful roasters at Ceremony) and barista proficiency of the highest order. Excellent machiattos and Australian flat whites. One warning: come for the coffee and conversation...there is no wifi at Filter.
