Where to host small birthday gathering in Chennai

Hello all, As the title suggests, I’m looking to host a small gathering in Chennai for my sister’s birthday over the weekend for about 20-25 people. Looking for a simple, non-veg restaurant in and around KK Nagar Area (surrounding areas are fine too) with buffet options preferably which would fit the bill. Currently looking at a budget of about 700-1000 rupees maximum per person, so any and all suggestions would be welcome. Thank you.
