I recently came across a quaint little dessert shop called "love and cheesecake" in Mumbai (they have outlets in Khar, Powai and Lokhanwala). I have always been on the hunt for a good cheesecake in mumbai - most places make a joke out of the cheesecake, but this place doesn't disappoint! Try the classic NY style or banana caramel (my favorite!) and you would keep coming back.
Thought I would just share.
PS. Full disclosure: a few of my buddies are involved in this venture. I've no economic linkage with them. :)
