All day Monday, Barrio (1420 12th Ave., open at 11:00am) features 1/2 off, that’s a big 50%, any and all tequila. The catch: This promotion is for learning purposes. With their selection of tequila, you could learn a lot in one night. The deal applies to shots of tequila served neat only, and the bar offers a small back of their home made sangarita (). I can dig it; if you’re going to give away the good stuff, the least you can do is make sure it gets to its new home properly. (Shot at right is neither a tequila neat or sangarita but a cool shot of Barrio’s Bloody Maria.)Come skate at the Rebar (1114 Howell St.) this Friday! With music by Kissing Potion and a rotating cast of DJs, Soul Food happens every first Friday of the month, and now it’s happening with rollerskates! No seriously, come skate before the whole idea goes tits up because someone cracks their head open. Maybe that someone is you! (Friday, July 3rd, 10:00pm, $8 admission, $6 in skates)
