"Starts At: $120 for two hours for up to 5 people A tiny karaoke lounge in Flatiron, Baby Grand has three private rooms, the largest of which can fit up to 14 people. But unlike most spots on this list, our favorite place to hang out is the bar up front. Swing by on a random weeknight, and you can bond with a few strangers while you all take turns singing songs at $2 a pop. If you’re planning a birthday, there’s also event space in the back with its own stage, starting at $1,050 for three hours." - bryan kim, neha talreja, molly fitzpatrick
