Chef Barbara Lynch’s Drink has been the stage for a generation of wildly talented Boston bartenders. Inside this massive basement room is three yawning bars meant for drinking. Behind one is a massive ice block that is slowly whittled down throughout the night for large format cubes and shaved ice. Behind another is a bartender making Southsides or Ward Eights or any number of classics. And behind yet another is a lady or gentleman setting overproof rum on fire in a bowl of Scorpion punch. And that’s not even to mention the thoughtful wine list and exceptional bar food. Drink is a split-personality bar in the best way possible.
