What’s the most fun / coolest class you’ve taken in NYC?

This was asked in the r/AskLosAngeles community, and I thought it would be good to ask the NYC community.
What’s the coolest class you’ve taken ? Thanks u/pandaintheparks!

“Can be fitness, writing, a craft, a unique fun class, what’s the best class you’ve had and that you recommend?” Include where and how much!
