"Barra stands out in Union Square’s exceptional food and drink scene with its contemporary, Mexico City-inspired fare and libations. The tequila and mezcal offerings are some of the best in Boston, and the cocktail list includes an unforgettable mezcal martini. It is presented in a lovely etched glass coupe, and features mezcal or raicilla — another agave-based spirit — dry vermouth, elderflower liqueur, and cured cactus." - Anna Darrow
