Uber may be only five years old, but it sure knows how to throw a holiday party like the rest of the Silicon Valley giants.

For Uber's bash, the ride-hailing company rented out the Pier 27 cruise terminal in San Francisco and transformed it into a silent disco party. There was an open bar, a doughnut station, and plenty of headphones passed around so employees could groove.

Even Uber's CEO Travis Kalanick made an appearance with a special guest, who clearly won best in show.

Here are some of the highlights from Uber's silent disco.
