I would add Degrees at the Ritz Carlton in Georgetown. Not sure what the crowd is like these days, but the fireplace is warm and the lighting sets a certain mood. I adore Proof, the restaurant, but there's not much room in the bar area. Hell, that might be what young hipster is seeking, but I felt I should throw that out there. Veritas is so happening that there's rarely elbow room there either. Still, I like the place.
