Since opening in 1998, Barbara Lynch’s No. 9 Park has made a big impact, not just on the culinary scene, but on the cocktail scene too. Now you can pull up a stool and learn the techniques, specs, and a healthy dose of history from some of Boston’s best bartenders. In this installment of No. 9 Park’s monthly cocktail class series, you’ll learn all about how British Imperialism spread spirits across the globe and made the cocktail revolution possible. Bar snacks will be provided in addition to the craft cocktails you’ll be shaking up. Tickets $95 plus taxes and fees.
