One Tiny Champagne Bar is located in the corner of Stockmann opposite the Svenska Teatern. It has cozy terrace which serves breakfast and as name says champagnes. Do not try to order other sparkling wines because they do not have them. Excellent place to observe passers-by.
One discovery during Helsinki Samba Carneval was Champagne Moet Ice Imperial from Moet & Chandon. This champagne breaks tradition you are not allowed to drink champagne without ice. You must also flavor the drink with fresh mint and lime or orange zest.
Champagne is served in white class which again breaks traditions. Ice cubes are in specially designed white bowl as well as “spices” in separate pigeonhole. Also bottle is white, carefully styled ensemble.
First impression was that this might be hit in the summer but it takes time to balance the taste. Maybe two citrus fruits are too much, lime seemed to suit better than orange. You also have to crunch mint because unbroken small leaf does not give enough flavour. Bar could add another mint leaf on pigeonhole which might also help. If you like lots of bubbles you may not like this champange because ice cubes naturally reduce them.

I tried this recently, but it was served without the fruit and spices, just over ice. All it did was water down the champagne! It’s not cheap either, you’re better off just getting a nice bottle that can be enjoyed on its own!
Thanks for comment! Tequila at Epcot must have been better?
I don’t know if I could ever go along with this! Ice in Champagne? Flavors?
Drink for ladies would say
