Movies, drinks, eats, doing stuff on water — Jack London Square boasts entertainment for pretty much everyone. And add dancing to that mix: During the summer, the Square hosts Dancing Under the Stars every Friday night. The party begins at 8:30 p.m., with a quick lesson before open dancing, and every week is a different genre. On July 21, for instance, you might learn line dance. Or on July 28, Bachata Latin sounds will take over. Don’t worry if you’re not a pro; dancers from all walks of life attend this event. After the lesson is when the real party begins. My advice: Make it a different kind of date night, complete with dinner and cocktails at one of the many restaurants on the waterfront, followed up with some dancing. Best of all, it’s free! Every Friday through August 25, 8:30 p.m., Broadway at Embarcadero West, Oakland.
