Bayou Bakery and Cafe is a New-Orleans themed cafe located at 901 Pennsylvania Ave SE (there is another location in Arlington at 1515 N. Courthouse Rd). It is one of my favorite spots in DC because it combines tasty food, reasonable prices and great ambiance. I go for their chicory au lait and beignets (a generous portion for around $3) and I stay for the warm interior of a Carriage House built at the request of President Lincoln. They also have real food (po’boys and such), but I haven’t yet tried it. There is ample seating, and it is a great, cozy environment for a winter day. Highly recommended – you feel like you’re in a farmhouse in the middle of DC.
