The Rattlesnake’s 25th Anniversary

Okay, so this is a bonus Taco Wednesdays-through-November special. Chef Brian Poe’s Kitchen at the Rattlesnake is honoring 25 years of the Back Bay watering hole with six weeks of throwback taco specials. Poe took over the kitchen in 2009, and he has culled from his recipe book for the “greatest hits,” starting tomorrow with Coca-Cola and molasses-marinated duck, nestled in a tortilla with cranberry-rosemary risotto, foie gras truffle butter, and cotija cheese. The game-inspired chef follows that up with quail; scallop; serrano-stuffed boar; lamb; and turkey tacos on respective Wednesdays through November 25. Plus, Rattlesnake’s signature “mini margarita” is on the menu for $2.50, its original, 1990 cost.
