Help Me Find a Piano Bar in DC

While in DC next week I'm trying to organize a birthday party/piano bar singalong for my pal Stacey. Is anybody out there a piano bar afficianado? We're looking for something as fun as the Mission Ranch in Carmel.

I've been doing a little research and have found a few leade ... any opinions? Perhaps we'll choose one of these.

Kinkeads Restaurant 2000 Pennsylvania Ave. NW Washington, DC. Directions

Telephone: 202-296-7700

Mr. Smith's of Georgetown

Washington, D.C. 20007

or maybe

The Ritz-Carlton
1150 22nd Street NW

Two words: sch-wank. This is where you go for The Royal Treatment. The cocktail service is impeccable, and the multiple seating areas surrounding the piano area are dark-walled paradises where you can ensconce yourself, oblivious to others, no matter how crowded the bar gets. A weekend visit found the husband and wife team of pianist David Allen and vocalist Susan Allen, a polished duo who can meet the challenge of filling the rambling space without overwhelming it. "Misty" isn't their strongest number, as they lean toward crisp, jazz-lounge takes on '70s pop. A Carole King medley? "You Don't Bring Me Flowers?" Oh, yes, bring it on. The Ritz-Carlton boasts piano music by a variety of artists seven days a week, starting around 6 p.m. daily. You gotta try this at least once in your life.

Stacey and I are checking in to the Hyatt Regency Capitol Hill on Monday.
