Six food facts to know about San Francisco tech company cafeterias

Dropbox chef Brian Mattingly has an ego befitting a man who formerly worked for Michelin-starred restaurants and headed culinary programs at Apple and Google. He spent months perfecting the burger he serves daily at his Dropbox cafe, Tuck Shop, eventually settling on a blend of brisket, chuck and jowls. He believes the work has paid off. “Our burgers are the best in America,” he says.

In fact, Tuck Shop briefly appeared on Yelp and garnered such high ratings from Dropbox employees that one night, a group of prospective diners arrived from San Jose thinking it was a real restaurant. Mattingly was so embarrassed that he gave them $100 to find dinner elsewhere.
