At two in the afternoon, Rovaniemi is a warm 12 degrees below zero. And I&rsquom warming up for a culinary rite of passage. The capital of Finnish Lapland lies at the edge of the Arctic Circle, the imaginary line plotting the southernmost reaches of the midnight sun. Razed to the ground by retreating German forces in World War II, Rovaniemi was rebuilt on plans by Alvar Aalto, the Moominpapa of Finnish design. And so the streets that famously spread out like the antlers of a reindeer. At what is touted as the northernmost McDonald&rsquos in the world, I dig into my first quarter pounder ever. I&rsquom lovin&rsquo it.
