Every trip to Finland requires going to the market square in downtown Helsinki at the edge of South Harbor and getting a Lihapipiirakka. Of course, you need to get the best, and the 'Toripojat' serve up Finland's best and since it is a Finnish pastry (of sorts), you are going to be hard pressed to find any better outside of Finland.
You can find a picture of one here. I will post a photo of one if I manage to get another one. I was unfortunately too hungry when I got mine today to get a picture of it!
