I would say Gaming cafe would do better because if you look games like dota2 / CS :GO / 1.6 they are addective like anything and school and college students would anyways come to the cafe while they are bunking .
I have a few ideas about this to help you out,PM me if you want to know.
P.S. : I'm currently in Mumbai
If you need help with setting networks and servers for the same, do let me know.
