The biggest news in the restaurant world this week is the initial public offering of our very own Cava Group, which got its start 17 years ago in Rockville. CEO Brett Schulman rang the bell at the New York Stock Exchange on Thursday morning, flanked by founders Ted Xenohristos, Ike Grigoropoulos and Dimitri Moshovitis. By day’s end, the company had raised $318 million. Much of that money will be used to continue Cava’s expansion. Long-term goal: 1,000 U.S. locations by 2032.
