Gandía, Spain, for the most stunning seafood dish I have ever eaten, arroz a banda at a small restaurant that I doubt I would ever be able to find again (nuts!) This meal is still reverberating in my tastebuds 11 years after I ate it.
Intercourse, PA, the annual Mennonite Auction to benefit Haitian Missions, for the doughnuts alone. They are positively transcendental.
