Dance class recommendations in Kolkata?

Looking for something social rather than serious. Salsa, or anything where you switch partners.

Don't push through. Say it was nice, finish your coffee, go home.

I always do the video call. Five minutes tells you more than fifty messages.

Two coffees, then decide. No dinners for a first meeting, you're stuck for two hours.

Book something with an end: a gallery that closes at six, a class that finishes.
