I really want to spend my weekends on unique experiences. May be sometimes weekday evenings too. How you guys usually find such?

Oktoberfest

Is there a better platform than BMS to find it? Instagram reels I save it, but difficult to find when needed.

You can search for different events in BMS. There are various meetups like rafiky, cubbon meets, small world, etc. This weekend there are a lot of garba nights around blr.
