Zingerman's Next Door is an extension to Zingerman's Deli, with two floors of dining space, as well as cases of pastries, gelato, and chocolates. It's also where you go for coffee or tea.

ZingTrain sometimes uses the upstairs space as training space, and Zingerman's often does tastings upstairs.

The bulletin board upstairs consistently has good and interesting postings.
