I tried yesterday http://www.murudining.fi and I say we have a new best restaurant in Helsinki, at least when it comes to quality of food compared to the price. The menu changes very often, they take great pride in coupling nice wines with the food, and the service is genuine and unpretentious! In addition, it's very affordable. I had a glass of cava, 4 course meal (poached egg with truffles, slow-cooked lamb confit, cheese and white chocolate mousse) with wines (Riesling, Amarone etc) and espresso, and the final tab was well under 100€. That is an extremely good price for food and wines of that quality.
