Dinner party on sat,,need help

normally if i have a dawat I make chicken biryani, kadhai gosht, shami kabab, pasta, mixed vegetables.. as u see.. a lil bit of everything but ive used this menu for 20 people. since ure cookin for 50, u should go for basics and less time consuming...
1) definitely biryani
2) definitely shami kabab (u can make 2-3 days before and fry them even before the guests come and microwave it)
3)Korma cus Kadhai uses alot of tomatoes!
4)Chicken drumsticks (marinate it all nite in a chicken tikka masala with alot of oil.. the next day cook it up.. the masala will dry up. take out the drumsticks from it.. serve!)
5) Veggie pasta...

I hope this helps :)
