CABARET: It's opening night of The Countess Katya Smirnoff-Skyy's Katya Takes You Home, a comedic romp around the world with "San Francisco's favorite Russian countess opera diva turned Macy's cosmetic counter lady," who has "enthralled Bay area audiences for years with her unique blend of opera, pop, and booze." The show runs through the 22nd. (8 p.m., The Jewish Theater, 470 Florida Street)

PARTY: Celebrate the end of another successful Bike to Work Day at SF Bicycle Coalition's Bike From Work Party at DNA Lounge. There will be DJs, raffle prizes, a fashion show, and complimentary valet bike parking, of course. (6 to 9 p.m., DNA Lounge, 375 Eleventh Street)

DESIGN: Twelve Academy of Art University's graphic design students present their solutions to the challenge put forth by Good magazine’s Good Design SF competition to identify and tackle problems that confront the Bay Area.
