If you feel the service is a little slow at your favourite hamburger joint, you may want to check this place out. They use a pneumatic tube system at C1 Cafe in New Zealand to deliver sliders to tables superfast. Like, 87 miles per hour fast.
Currently, the restaurant has 1 pneumatic tube delivery system set up to a table in their dining room, but plans are to have the rest done within a year. Tubes run along the ceiling and through the floor to have them magically appear in the center of your table.
