Need a suggestion for Budget friendly dinner spots

My friends and I (around 20 people) are looking for a place where we can have dinner while sticking to a budget of ₹300-400 per person on this Sunday. We're open to all kinds of cuisines be it South Indian or north indian, cafés, or casual dining restaurants as long as the food is good and the place can accommodate a group our size. The place should be near Rahul Raj mall or nearby. Would appreciate any recommendations, especially if you've personally been there and had a good experience. TIA
