It's last call, which typically means hitting the bricks, hitting up fast food, then hitting the sack, right? Maybe for you, quitter, but we're not letting the state-mandated buzzkill end our night. We're bound for Karamba, where after-hours adventures await and the party keeps going up until 4 a.m. on weekends. And once the taps are turned off and the booze bottles get stowed, the mood, music, and energy level at the popular discoteca (which has offered wee-hour wingdings for Valley insomniacs for more than a decade now) begins to change. DJ Jesus Vega holsters all the cumbias, salsas, and other Latin sounds in his extensive arsenal in favor of Top 40 music videos and uptempo EDM mixes. Meanwhile, 18-and-over types (who are allowed in after the liquor service ceases) begin to deluge the place, drain its energy drink supply dry, and get in some late-night booty-shaking alongside Karamba's always-colorful Latino clientele. Who says youth is wasted on the young?
