Each business has its own organizational structure, but they carry out the same standards and commit to the company's values.

[1] The Deli was originally to be named Greenberg's Delicatessen after a regular customer at Monahan's Fish Market, where Saginaw had been a partner with Mike Monahan,[4][5] but another business that had that name objected.

It opened a second restaurant, Zingerman's Roadhouse, which focuses on regional American cuisine.

Zingerman's sponsors several mail-order food clubs and occasional culinary study tours.

Zingerman's assisted Avalon International Breads with a substantial discount on the purchase of its old steam-powered oven as well as its original business plan when Ann Perrault and Jackie Victor established the Detroit-based bakery in 1997.
