Summer in the city is bikini season, sure, but it's also hot as hell. While beach-bound boys and babes are walking around half-naked with a salty ocean breeze at their backs, the rest of us are stewing in small apartments, sweating next to a harbor as smelly as we are. Enter Sylvan Beach, a small but seriously accomplished café offering up the city's best homemade fattening frozen stuff. And the best part of indulging at Sylvan? The café not only provides us yummy summer treats but also helps disadvantaged youth get a leg up in the business world. Employing graduates of Sylvan's rehabilitation program--offering life skills training in regards to housing, academic instruction, counseling, and career opportunities--the café takes the guilt out of indulgence. So if you find yourself there each week to try Sylvan's constantly changing flavor assortment, don't sweat it. Leave the diets to those at a real beach.
