I think I just found a new favorite cafe near DuPont circle. Say hello to my new friend, Emissary.
This by-day coffee shop and by-night bar with brick walls as their interior lets you quickly settle in feeling cozy. The space is a little dark, which is why I snagged a seat next to the window, but if you're ever in the area and need a study/work spot, you should definitely consider this location. They have a lot of space and even a nice, semi closed off, sofa area for a larger group in the back.
Although the food was a little salty for me, I really liked the ambiance of this place, loved my drink, and I really want to try out their lox & brioche next time I visit. Until then!
