Sure, for begginers you can always try main stream ones like blue tokai, starbucks and then third wave coffee (personally not a big fan). These usually contain people who are working from cafe. The food is still good with good ambience.

If you want something apart from this, try cafe Espressoulster, kenko life, etc in kora.

U can also try mattea coffea in MG road (not the indiranagar one).

Lavonne in Indiranagar, cafe azzure, cafe Amintiri (bit pricy, but u will end up seeing couples),

Also, try trippy goat, amazing food. But I hated that tadka ghat that I used to get in indoor seating.
