There are few experiences more genteel than enjoying cocktails in the Brown Palace Atrium: The space is casual, yet has a well-heeled charm augmented by the tinkling piano, super-comfy seating and a fabulous ceiling eight stories above, complete with skylights and chandeliers. And then the martini cart, covered with elite liqueurs and elegant silver shakers, drifts tableside to mix up a little something for you. The Brown offers cart service during the cocktail hour nightly except on Sunday, with later hours on Fridays and Saturdays, and it's a swell way to start off an evening on the town -- in every sense of the word "swell."
