I've developed the (lethal) habit of, after DiFara, walking across the street to Isaac's bakery. I'm definitely no connoiseur of Kosher bakeries, but everything I've had there has been outta sight. Granted it hasn't been much: a sweet roll, some unpronouncable chocolate coffee cake thing (amazing), a black & white. But the stuff's been astoundingly fresh and tasty. Haven't seen anyone else write about the place. So, is Isaac's just middling? What are the best bakeries in the nabe?
