Hanke Refrigeration Service, 1605 S 1st St, Marshalltown, IA 50158, US

Serving Des Moines since 1908, Hockenbergs Food Service Equipment and Supply features a retail showroom that Des Moines Branch Manager Dustin Tyler calls the company's "bread and butter." With booths, dinnerware and lifelike table settings, the showroom provides a realistic picture of what Hockenbergs' products would look like in a restaurant's dining area. The rest of the store contains appliances ranging from coffee makers to industrial-sized refrigeration systems as well as a full-service test kitchen. While Hockenbergs serves clients such as Applebee's, Caribiou Coffee and Taco John's, the building is open to the public for browsing and shopping as well.
