A Halloween-themed cocktail pop-up “where mixology meets the macabre” will creep into the Alamo City this fall as part of a tour hitting 35 cities across the U.S., Canada and Mexico. Black Lagoon, a concept launched by bar-industry veterans Erin Hayes and Kelsey Ramage, will possess San Antonio’s Three Star Bar from Oct. 11 through Oct. 31, bringing along Halloween-themed specialty cocktails, chills and plenty of creepy decor, according to organizers. Hayes and Ramage conceived Black Lagoon after a successful horror-themed pop-up at The Dungeon, a New Orleans drinkery known for its dark French Quarter vibes.
