At 8:05, Bill Murray stepped in at last. The place lit up with smartphone flashes as he moved toward the bar. Those not occupied with capturing his likeness for their Instagram accounts gave him a round of applause.

His first order of business was to grab a bottle of Slovenia Vodka from behind the bar. He twisted off the square black cap, poured a shot into it, drank it and placed the cap on his head to big cheers. Then he got to work.

People who shouted the names of complicated cocktails got nowhere fast. But when someone said, “Mezcal, rocks,” the guest bartender served it up chop chop. Mr. Murray was equally quick with tequila shots, for himself and for anyone who asked.

The co-owner of the bar is Bill Murray’s son, Homer. Homer described his father’s bartending skills:

A mixologist simply knows how to mix drinks…A bartender knows how to run a bar: interact with guests, have fun, have conversations with them. Bill is a bartender.

The whole story reads like a script from one of Bill Murray’s movies (most notably, perhaps, Lost in Translation).
