This is the rhythm of the night. Luscious chunks of Yucutan-style pork, plopped onto steamy corn tortillas and slathered with a salsa of pico de pajaro chiles and wisps of crunchy cabbage. You're sitting on the deck watching the sun go down behind the glistening office towers. There's techno, and fish tanks ...   

And hey, did we mention it's free? At The Aquadec Rooftop Lounge on Friday nights, all you've gotta do is buy a $3 drink, and the "Taquito King" Ruben Soto will cook you up something incredible. Today it was his cochinita pibil tacos, with pork marinated in achiote chile, orange juice and Tecate beer. Then slow roasted for eight hours in banana leaves. My god, do I even have to describe them again? I know I have a great job, but this is torture! 

Weird fact: I just wanted to apologize to the guy who really loves Ruben's chicken wings, which got pushed off the menu because of this taco project ... Maybe next week?     

Location: 61 E. Congress St. 

Hours: 5 to 9 p.m. Fridays

Payment: All you gotta do is buy a drink at the bar!
