Cinco de Derby, Derby de Mayo, Cinco Derby — whatever you’re choosing to call May 5th this year, celebrate Saturday at Precinct Kitchen + Bar. The Back Bay bar, nestled within the Loews Hotel, is hosting a dual-purpose party from 3:00-7:00pm with drinks samples (like a Mint Julep and Caballo Picante) and free swag from Don Julio Tequila and Bulleit Bourbon. DJ Obie will provide live music, so be ready to dance whether inside or on out Precinct’s awesome patio. Hats and bow-ties are encouraged (there’s a contest for best dressed). Call 617.532.3827 with any questions.
