Good chocolate babka is a special treat and the chocolate babka from Russ and Daughters is amazing. Kind of a mix between a bread and pastry, infused with chocolate, a chocolate babka typically comes in a loaf. Russ and Daughters sells wrapped chunks and I can't recall seeing as much chocolate as they stuff in their babkas.

Here are some yummy looking, other babka offerings in New York City, and more here at Serious Eats. Russ and Daughters isn't on either list, probably because it's more of a deli than a bakery. But if you happen to be on East Houston Street in Manhattan, over by Orchard Street, pop in and try a hunk of this chocolatey goodness.
