Chances are, you’ve probably never spent your New Year’s Eve inside a swanky bowling alley, so consider this December 31 your lucky day. The 2015 festivities include friendly casino-style gambling tables (where you’ll need some of that luck), a “cash money balloon drop,” and a complimentary champagne toast for all the revelers who ring in the new year with spinners DJ Ronny Romero and DJ Hardy. Lucky Strike, 200 King St (415-400-8260,bowlluckystrike.com). Dec 31, 9pm. $25-$65.
