Housed in a historic Girard Bank landmark that features a domed-ceiling entrance and gorgeous glass chandeliers, the Ritz-Carlton is possibly the most striking hotel lobby/bar in the city. And even if you're not on an expense account, the generously portioned martinis are worth every penny.

Located in the former "Library Room" high atop the Park Hyatt at the Bellevue, this sleek, elegant bar is a sophisticated sanctuary. With leather banquettes, a mirrored wall and dark wood tables, it's the perfect hideaway if you're seeking reasonably priced, strong cocktails after work or after hours.

Classic yet casual, this quiet hotel lobby/lounge offers great views of Old City. The warm atmosphere is perfect for sipping cocktails on the plush couches and armchairs before or after a film at the nearby Ritz theaters. The bar itself isn't fancy, but it's affordable, and the staff is friendly. They make a great stinger (brandy and creme de menthe) in the winter.

After the dinner rush ends, this happening hotel piano bar—with karaoke every Tuesday—features Stu Shamas, a classic-rock piano man playing showtunes and sing-along hits like "Brown Eyed Girl." Sing 'n' sip well after midnight.

This quaint bed and breakfast, built in 1832, may be known more for its fine bar than its beds. The remodeled gastropub, located on the ground floor, features local favorites like Flying Fish, Dogfish Head and Yards on tap, along with an international wine selection. The hotel also offers one of the best outdoor table areas on a bustling, "be seen" corner.
