I'm coming to Chembur in September

I'm going to visit Mumbai beginning of September, I'm coming from Portugal. I'll be staying in Kurla for the first 10 days then heading to Delhi, then back to Mumbai but have not booked a place yet when coming back so no clue where I'll be staying. Looking for ideas of things to do out there that's not your typical tourist trap type of stuff. I'm still getting used to Indian food, the spices... it's too much! But I've come around to trying some of the chutneys which I thought would never happen and everything I tried was good! You guys just love everything gravy style, it takes some getting used to. Anyway, I'm open to suggestions.
