The Bar/Lounge at Hotel Atlantic Hamburg, Autograph Collection

"Of course, many of the guests could care less about costs: Madonna, Mick Jagger, Elton John, and a long roster of other notables stay here when in town, as do savvy travelers who feel at home in the surprisingly cozy lounges, sophisticated art deco bar, and guest rooms well stuffed with comfy arm chairs and plump bedding"

"That aside, the romance of the place is inescapable—you could drive a truck through the sconce-lit hallways, and the bar is a dark-wood international watering hole with a menu full of obscure Champagne cocktails, such as a Prince of Wales (invented in 1936, it combines Courvoisier, Cointreau, and a dash of Angostura, then is filled up with Champagne, garnished with fresh fruit, and served in a silver cup)"

"The impressive on-site restaurant serves German fare and seafood, while the bar is a popular spot and often features live piano music"
