How’s your drop shot, your top spin and your lob? Good enough to get you into an Olympics ping pong game? If you need to polish up your talents join the games this Friday-or any August Friday- from 12-5 at the SPIN Ping Pong Social Club on Folsom Street in the City. Even though it’s in the middle of the day, you get happy hour pricing, not to mention assorted prizes. I’m not sure how professional you’ll sound if you call it table tennis.
