Via the comments, a Bosco rep has kindly answered our call for information about the availability of chocolate soda, and the situation is just as dire as we thought. Within the five boroughs, Bosco is only available at 2nd Avenue Deli, Ben’s Kosher Delicatessen, J’s Papaya in the Bronx, and Joe’s Best Burger in Flushing. Brutal. Just brutal. Restaurateurs, we implore you to write to the commenter at his boscoworld.com e-mail address (Boscoworld, how cool is that!) and get onboard with this fine product.
