Have a house party!!!
You can visit a club and have get together. For partying you can do house party
Rent some place and party there without any restrictions, it's the best
Try cafe in southex, greenpark,sda,hauz khas
Diggin, Ama cafe and cafe wink!
Most of the cafes are open now and following all the safety precautions. Personally, I prefer 1oak or Urban Room
