Chef Jose Andres' Barmini (Washington, DC)
Chef Jose Andres not only has a group of some of the best restaurants in Washington, DC, but also one of the best cocktail bars in the city. Barmini is a small, beautiful bar right next to Minibar. You have to be seated and most of it is reservation-only but they do allow walk-ins if there are seats available.
The drinks here are more expensive than usual, but everyone that comes in gets a free welcome cocktail. The night I was there, the welcome drink was a 19th Century Cocktail: bourbon, lemon, creme de cacao, lillet rouge
There are quirky details that I love here, like this suspended chair, and other things you'd see later.
