This is one the World Desing Capital Helsinki 2012 offers. There are also many WDC menus available in the same restaurants. Usually you do not get bottle of champagne under 60€ in restaurants.

But you have to own S-Bonus card to get the bottle for offered price.
We tasted this champagne at Restaurant Kaarna and found it tasty and crispy.
You can not even buy this champagne from Alko which is an independent limited company wholly-owned by the Finnish Government and administered and supervised by the Ministry of Social Affairs and Health. You can find Alko price list in english behind this link http://www.alko.fi/products/hakutulos
