Thankfully, in this heat, ice cream hasn’t been left out of the sandwich trend. We’ve compiled the top seven nouveau ice-cream sandwiches in town. If you want a pure classic, however, try the Smithwich at the Smith, with its housemade ice cream and chocolate-chip cookies. You can grab it and go from the walk-up window on Third Avenue. Or consult our favorite ice-cream sandwiches from 2006. The options are endless in the summer of sandwiches.
