Eat the Wagonwheel.

Fancy a little Baltic snack? Help yourself to the nahkiainen - dried lamprey eel. Nami nami. Today marks the opening of the Baltic Herring Festival, where you may also find some nahkianienen. Hopefully I will get down to the Market Square to see all the winners at 3.30pm. Herrings not only look yummy but can also contain your daily requirement of toxins.
