Suggestions for a main course for Friday nights dinner?

We want to have a bit of a celebration dinner tomorrow night (Fri) after receiving some good news. The starter is sorted and that will be fish. The problems for the main course are: We are sick of steak (pork, lamb or beef), stews, ceroles and ragouts, fish pies, stuffed chicken wrapped in ham or whatever, lasagne's, baked pasta dishes and curries et al. We desperately need something different and most of all, exciting. Can anybody out there direct our jaded pallets to something that will knock our socks off without spending all day in the kitchen. Thanks.
