Sun’s out, swords out at Catalyst in Cambridge on Tuesday, September 17th for a patio party with Louis Roederer Champagne. They’ll be popping (and sabering!) the full lineup of Roederer’s seven champagnes in the sunshine from 4:00 to 7:00pm while you mingle and make your way between food stations. They’ll be shucking fresh Chatham oysters at the raw bar and passing tasty apps to pair with your bubbles. $95 gets you in the door; save the date right this way.
