Chef Jason Santos brings his New Orleans-inspired concept to Back Bay just in time for Mardi Gras. Buttermilk & Bourbon opens its doors on Feb. 24, with rooms inspired by the southern city’s most famous neighborhoods. The offerings include New Orleans BBQ Shrimp, oysters prepared Louisiana-style, and of course, beignets all day. They’ll also be serving hurricanes on tap (!!!) and frozen hand grenades, the extra boozy, melon-y favorite that is probably the reason what happens on Bourbon Street stays on Bourbon Street. 160 Commonwealth Ave., buttermilkbourbon.com
