The best: My brother's wedding. His wife is Turkish and they got married in Turkey. I have no idea what most of the food was. All I remember (this was 15 years ago) was each dish was more delightful than the last. And there were so many of them! All while we cruised around the Bosphorus on a boat as the sun set. That whole wedding was just the best.
Really good runner up: My cousin's wedding where they had several different food stations. The one I remember was the mashed potato station. They put mashed potatoes into a pastry bag and filled sundae cups with swirls of potatoes. Then you added the fixings of your choice--butter, sour cream, a couple of different kinds of grated cheeses, bacon bits. Somehow they kept the potatoes piping hot.
Best wedding dessert: Another cousin had a chocolate bar for dessert. You know, like a salad bar, but with chocolate desserts--pudding, mousse, cakes, ice cream, souffle, whipped cream, chocolate sauce, little hand-dipped chocolates, strawberries dipped in chocolate, and a few other things.
