Re: What's the American gora equivalent of the Biryani?
From an English pov, I would agree with maroush and nadimnirvana - Chicken (Roast or otherwise), salmon, beef or steak.
I will repeat SALMON again, as no self respecting Angrez would be without smoked salmon or salmon something else at their wedding.
(Unless u r "Mo" from "Eastenders" who would of course be very pleased and excited to serve tinned salmon filled sandwiches.)
