Insa is an upscale Korean barbecue spot in Gowanus that’s perfect for groups. But if you and your people don’t all live around here, you’re going to need another reason to come all the way out to Gowanus, right? Good thing Insa has that need covered too - with karaoke. After you sit at a big table and grill lots of meats and eat kimchee fried rice and seafood scallion pancakes with all your friends, rent out a room and sing all the songs you liked in high school.
