Restaurants for celebration

Hi all, we are a group of 8 adults and a toddler from NY. We are well travelled and exposed to different cuisines. We will be in Mumbai next month to celebrate my aunt's 70th birthday. 10 years ago, we went to the Rambagh palace in Jaipur to celebrate her 60th birthday. That dinner was epic. I am wondering if you have any recommendations for a dinner spot in Mumbai that would be comparable to the Rambagh palace in Jaipur. And a place that allows toddlers. We checked with Indian Accent and Masque but they do not allow kids. The restaurants at the Taj Mahal hotel seems interesting, but I wonder if they are celebratory in their vibe. For reference, our dinner at the Rambagh Palace was also quiet, but the place was just so special and the service was exceptional. I understand that the Oberoi has a couple of decent restaurants, but I am not sure if they have the energy of a high end but fun place. We don't want to go to a fancy place that's uptight or quiet. But we do want the place to be unique and special and celebratory without being tacky. I also looked up the Duk Pukht restaurant at ITC Maratha, but it did seem quiet. Of course I have not been there, so these are impressions from online search. In a nutshell, can you recommend a restaurant that's fancy, energetic, with great food, and which would be special enough for a big milestone celebration? Any recommendations?
