Start practicing your backhand: The Susan Sarandon-backed, self-described "ping pong social club" Spin softly opened Monday night in San Francisco.

Joining a bevy of adult playgrounds currently saturating the Bay Area (see also Plank in Oakland, Urban Putt, Brewcade and Mission Bowling), Spin, which is owned in part by Susan Sarandon, is scheduled to have an opening party at 690 Folsom Street on May 19.

In the futuristic building at the corner of Folsom and Third, Spin boasts two bars, a kitchen, multiple private rooms, and 16 ping pong tables. Chef Mike Betancourt is in charge of the kitchen, and you can expect San Francisco-themed bar-friendly fare such as hot dogs, pizza, and sliders along with a full menu of liquors and cocktails.

Customers can book tables by the hour ($19-$29 for 30 minutes and $29-$49 for an hour), and group rates are available for parties. SPiN also offers private ping pong lessons from table tennis pros, including 14-time Swedish national champion Malin Pettersson.

Similar to Urban Putt and Plank, Spin is open to anyone during the day, but evenings are restricted to ages 21 and up.

SoMa is the chain's sixth global location, joining ones in New York, Toronto, Los Angeles, Brussels and Chicago.

// Hours will be Sunday-Monday 11am-12am; Tuesday-Wednesday 11am-1am; and Thursday-Saturday 11am-2am. 690 Folsom St. (SoMa), wearespin.com
