For me, the Churrasco in Brazil wins Best In Show for the food category. I almost didn't get it, because it's not that exciting on paper, but I went for it after a lady in the Mexico line raved about it to me. I'm so glad I did. The churrasco was perfectly cooked (a beautiful ruby red medium rare), tender, moist, and flavorful. Better than anything I have had at a fancy Brazilian steakhouse. I ended up going back twice more over the course of the day to get it again. There was some of the trademark FWF inconsistency: the second time I went, they told me they were out of the chimichurri sauce that goes on it. I said that was fine, and when I got my order it had chimichurri sauce on it anyway. And one of the times I had it, it was more cooked (like a medium rather than medium rare), but I think it was even better that way--more tender and it picked up more smoke flavor from the grill.
My Epic Fail award goes to the Mamon in Philippines. It's supposed to be a butter cake with cheese and raspberry sauce on top. I thought salty cheese on a sweet cake sounded interesting, and it was one of the few dishes on the whole FWF slate that I wasn't already familiar with, so I ordered one. When it came out, there was no cheese on top. I asked the staff at the kiosk, and they just shrugged and said nobody gave them cheese or told them to put it on there. Complete waste of $4.25. They should at least be telling people when they order that they're not going to get the dish as advertised.
