Some of San Francisco's robot-run restaurants are failing. It could simply be that we still want to be served by humans, not machines.

Creator is the world's first robot-made burger spot. This is what the burger bot looks like.

And this is CafeX's robot barista. The coffee company's San Francisco locations are now closed, so you can only check it out at two Bay Area airports.

The same goes for Eatsa — its San Francisco locations gave customers a futuristic dining experience before closing in mid-2019.

Over at Creator, "robot attendants," or human employees, take customers' orders on devices. The status of each customer's order could be tracked on a counter tablet.

At CafeX, customers ordered at digital kiosks.

The process was similar at Eatsa — you ordered via a tablet. When Business Insider's Melia Russell visited in 2016, there were eight bowls to choose from, all priced around $7.

Once a customer orders, a brioche roll from a local bakery is pushed through an air tube into a chute at Creator.

It's toasted, buttered, and is dropped into a to-go container. Ingredients, like smoked oyster aioli, charred onion jam, and "delightful shreds" — not slices — of cheese, are then placed onto the burger, according to the specific customer's order.

The Creator bot can have your burger built in under five minutes.

It was the same deal at CafeX. A $3 cappuccino was delivered via a tiny hatch in no time at all.

You received your Eatsa bowl in a similar fashion, via a small locker. The customer's name appeared on the front of the window, which meant the order was ready for pick-up.

Eatsa marketed itself as the "future of restaurants." It may have been a unique, futuristic experience, but as Melia Russell reported, it wasn't as though a robot was wheeling your order out to you. Unseen human employees worked incognito behind the lockers and deposited food orders while the window flashed black.

Russell said her Balsamic Beets Bowl was hearty and refreshing when she gave it a try in 2016.

Eatsa, Russell wrote, was perfect for people in a rush who value a wholesome meal at an affordable price more than human interaction.

But, alas, the company's restaurants are no more. Eatsa announced in 2019 that it was closing its San Francisco locations to focus on selling its technology to other restaurant brands. It was also revealed that the company owed thousands in unpaid rent.

With CafeX, Zume Pizza, teaBOT, and Eatsa now closed, Creator is one of the last automated restaurants left standing in the city.
