There is parking space but it fills up as the night starts so book a cab if you wanna drink hard and party harder.
Relive Your School Days At Gurgaon's New Bar, The Classroom
I went to The Classroom recently, as it's a newly opened brewery. Their decor and ambience is what will appeal you the most. Everything there would remind you of your good old school days. The school-style benches for sitting, a bar counter that looks like Ramu kaka ki canteen, a menu card designed like a textbook, the periodic table on the bar walls, and more: it's all super nostalgic.
Do check out their terrace seating area, it's open air and awesome.
