JPMorgan opened a bar for employees. If only they could get in.

When a tray of Guinnesses was served, the people overseeing America’s biggest bank noticed a familiar face floating on the foam: Jamie Dimon’s.

A JPMorgan executive had told the bar’s staff to use a high-tech printer near the taps to put Dimon’s likeness on the heads of the stouts, hoping the boss and his friends might appreciate the joke. Dimon, who turns 70 next month, thought the prank was amusing. But he banned his mug from appearing on Morgan’s pints, worried it would suggest the bar in the $3 billion headquarters he helped build was some kind of vanity project.

Now, the bartenders stamp beers with images of the Park Avenue building or seasonal icons like a pumpkin. The foam fiasco was just one of the first hiccups since JPMorgan opened a bar inside a Manhattan office building. Dimon was personally involved in the design of Morgan’s, where he toasted the building’s opening last year with lead architect Norman Foster, the man behind London’s Gherkin.

“We’re quite happy we did it," Dimon said in January when asked about the building. “We got Morgan’s Pub, Guinness beer."
