Unless you're still struggling with that bra strap, the foundations of your adolescence (e.g. 6-foot hoops you slammed on, the base system for bragging about boob) are by now sadly obsolete. Making a return to relevance, On the Corner.

Once a no-ID Mecca for kids from as far away as Marin to illicitly procure liquor, OTC's a spacious, high-ceiling'd & mahogany-floored café and jazz lounge sporting a black marble espresso bar, leather couches, vintage pendant light fixtures, and a Brio train set -- a consolation for those so young they need to shoulder-tap for a caffeine fix. Entertainment-wise, the owner's booking neighborhood jazz musicians to play sets Thu-Sat evenings (piano's provided, but it's BYO horns/guitars/skeetlibeebopdoowop). Food-wise, OTC's got your standard spread of from-scratch baked goods, while the bevvies surpass typical fare: Chemex-brewed joe from six different blends, house-made chai, espresso specialties, and cast iron pots of SF's oldest tea, Red Blossom -- crafted locally since long before the Tang Dynasty helped our astronauts conquer space.

In a few weeks (liquor license pending), OTC'll serve beer and wine and stay open 'til midnight -- until then you'll have to surreptitiously brown-bag it, though you'll be discovered while loudly bragging to friends about having recently stolen third.
