Events this weekend?

My son and I will be in Mumbai this weekend, tagging along with my husband who has a work event. Any suggestions for what we can do/see? I see there is the Da Vinci immersive - is that any good (we did the Van Gogh one, and were not floored). We will check out the NMACC, but any pointers on small, more niche events? Or anything else really that a 10-year-old might enjoy...
