Lawn/restaurant suggestions for 300 people.

Hi! My family is planning my nana nani ka 50th anniversary celebration. We need veg/non-veg both with DJ. People - 250-300 We have seen lawns going out of our budget so we are looking for restaurants with above occupancy. I have inquired in "The Food Garage" they said 500 per plate non veg. I need more suggestions. Please feel free to ask more questions.
