Please recommend a perfect night out in San Fran to celebrate my 29th birthday. Where are the best bars and night clubs with class in San Francisco?

Beach Blanket Babylon at Club Fugazi. A San Francisco tradition for over 29 years.

For clubs, try Matrix-Fillmore or 111 Minna. For a great bar scene, try the Lion's Pub. All are considered "see-and-be-seen" type of places (even though I cringe to use that phrase) and you can definitely get your party on at any of them. You can check them out on citysearch or sfstation.com. Happy Birthday!

If you want a great swanky tiki lounge go to the Tonga Room at the Fairmont.

It's seen better days, but it's still a blast.

We seldom make it to 9:00 in SF anymore.

Plus, "classy" and "Kal" usually aren't used in the same sentence. #39;(

Moose's, Wash Sq Bar and Grill, Carnelian Room at the top of the BofA bldg, Cityscapes, Compass Rose Room at the St Francis, The Redwood Room @ The Clift, The Grand Cafe, are some of the nicer places that won't let us in anymore.
