The Rattlesnake opened its doors in the Back Bay in 1990, occupying the small second floor and rooftop patio at 384 Boylston Street. Within three years, The Rattlesnake was so popular that the owners expanded operations to occupy the first floor, more than doubling capacity.Today, Poe's Kitchen at The Rattlesnake is open seven days a week to serve lunch, dinner & a myriad of specialty drinks. The outdoor patio is open to the public April through October, accommodating 50 people with a full bar and menu available. New to the Rattlesnake is the street level outdoor patio.
