Lox of love! New York's Grub Street reports that Ben's Kosher Delicatessen is expanding to Boston. Grub notes that it's one of a mere handful of kosher delis left in New York (and needless to say, there are even fewer in Boston). The Long Island-based chainlet offers the essentials like chopped liver and gefilte fish, plus there's a full bar. No word yet on location.
