One of the strangest devices ever seen at the Minnesota State Fair was Baitinger's Automatic Eater. A kind of mechanized restaurant, the Eater consisted of a 150-foot-long counter along which moved a procession of eighty-five wooden cars propelled by a system of cables embedded in a groove in the surface. The cars held food, and diners snatched for their favorite dishes as the train coursed past. Some cars had drawers filled with ice, to keep fruit or celery fresh; some were warmed with heated soapstones.

The ensemble was the invention of the Reverend J.M. Baitinger, an Evangelic churchman, who stationed himself out in front with a megaphone to ballyhoo a new era in state fair dining: "Haba! Haba! Haba! This is the place to be merry. Eat! Eat! Eat! All you want for 50 cents; for without a full stomach you cannot enjoy the fair. Haba! Haba! Haba!"

The Automatic Eater cost Baitinger more than one thousand dollars to build but, because of its novelty and the economies it permitted, the cafe more than paid for itself during a trial run conducted on the last few days of the 1920 fair. "Through the medium of the Automatic Eater," he stated the following summer, "I do away with all excess help and employ only one cook, a dish washer, and a woman to keep the train well stocked with food. I pay no attention to what my customers eat, how long they stay or how much food they consume." But there were healthy profits, which Baitinger turned over to a St. Paul hospital.

Baitinger's Eater was, in many ways, a perfect expression of the mentality of the automation-mad 1920s, obsessed with speed, technology, and efficiency. There were minor drawbacks to the system, however. Diners seated near the end of the line sometimes found that the only cargo left for the eating was boiled cabbage.

In accordance with our invention, the customers are provided with seats and if desired footrests moving in a continuous manner along with a table or like surface, the different courses being placed upon the table at definite positions in the travel of the table so that when the traverse of any particular seat is completed, the occupant has completed his meal and may move to a seat in a lounge or the like to rest and/or to finish his meal with a coffee or the like which may be supplied just before the said traverse is completed.

Anyone who’s ever attended a wedding might be wondering how you keep an open-bar concept from getting out of control. Butler says he’s put a few safety measures in place. When patrons book their time at Open Concept, they create a profile and are assigned a confirmation code, which is used to place drink orders at the bar. Bartenders will only serve one drink per person at a time, and a proprietary point-of-sale system will track consumption. Butler says the system will scan driver’s licenses and use a patron’s height and weight to assign a number of drinks per hour to keep the bar in compliance with legal limits.
