At Kenmare and Cleveland, a block party is getting underway in front of La Esquina, the super-hip, faux taco shop. Not-for-profit art gallery Storefront is setting up a soundsystem, and projecting ABC on the giant wall above the restaurant, which is giving out free hot chocolate. The big news? Storefront director Joseph Grima says that Patti Smith might come by and play a few tunes. (Wondering what time? He’s hoping for sometime between now and 9.) Also expected: neighborhood regulars Andre Balazs, Rogan (the designer) and Taavo Somer, of that other hipster fave, Freemans.
