How do u make friends in a new city? what options does Bangalore have apart from work,clubs and dating apps

Just talk to anyone on the street with a laptop bag.

Bangalore is full of lonely people, people are desperately looking for friends

Join a grp like hiking, cycling, books or whatever is your interest. There are also foodies grp, conservation grps etc. Find an event through contacts/media and be there physically to connect and find stuff that you really like and ull naturally find lots of like minded people.

do sports/gym come under clubs?

I made a few friends through reddit. It's a good way to find people with similar interests (because you follow the same subs etc),
