Boston’s Big Night Entertainment will open a tequila bar and restaurant next month at Foxwoods Resort Casino in Connecticut. The 5,000-square-foot Scorpion Bar will accommodate up to 300 patrons and have a 50-foot-long bar. Live entertainment will be offered nightly. Said Big Night principal Ed Kane, the Scorpion Bar “has a significantly darker feeling than what you think of a Mexican cantina, with some ‘Day of the Dead’ elements, but not colorful and festive looking. Everything is a little out of place.” DJs will play remixed rock songs from bands like Aerosmith, the Rolling Stones, AC/DC and U2. Big Night investors include Boston Red Sox Chairman Tom Werner and Vice Chairman David Ginsburg and auto magnate Herb Chambers.
