Kewpee Hamburgs Fast Food Chain-- Part 1: "Makes Your Heart Go Flippety-Flop"

From the October 10, 2014, Shorpy  "Kewpie Hamburgs: 1930."

Photo of one of their hamburger stands (only they spell it "Hamburg."  "Circa 1930.  Kewpee Hotels hamburger stand.  This early  fast-food chain ("Hamburg / Pickle on Top / Makes Your Heart / Go Flippety-Flop") got its start in Michigan in the 1920s.  Location and photographer not known."

Looks a lot like a White Castle.  Not sure why they referred to it as "hamburgs."
