Sorry I missed a lot of responses while I was there. But I did meet some hardcore HIFK fans, and they introduced me to Finnish homemade shots.
But both games were tremendous, with one caveat: they don't let you take beer down to your seat during the game?!? I thought it was a bit unusual when I got to the Jokerit game and I apparently had "club seats" where I was in a private section of the stadium with a really nice bar and beers served in glasses. But I found out quickly enough, there is no alcohol allowed into the seating area. Mind blowing. And a cattle rush between periods for people to order and slam their beers.
Regardless, magnificent city, unbelievably friendly people (who know how to drink), and just overall a great time. I enjoyed myself immensely while I was there. And both Jokerit and IFK won!
