Ben’s Soft Pretzels, a national pretzel franchise with both brick-and-mortar stores and food trucks, is coming to the metro area. Local franchisees Benjamin and Melissa Gaul are launching a Ben’s Soft Pretzels trailer on May 8th. It will be based in Gretna but will serve areas in Nebraska, Iowa and South Dakota. The brand is known for Amish-inspired, jumbo soft pretzels and has an existing metro-area location inside Vala’s Pumpkin Patch.
