Aino is a traditional Finnish restaurant in Pohjoisesplanadi. I have eaten there several times and have always found the food to be delicious. The service is friendly and helpful.
Their bread is baked on the premises and is very good.
Salmon soup is a favourite of mine when I visit Helsinki.
The salmon is also excellent.
Pannacotta is another favourite.
The location is excellent and the prices are reasonable. It is one of my regular places to eat when I am in Helsinki.
