As an ex chef who has lived and worked in the Finnish culinary industry (large scale catering and restaurants) but now sadly retired because of ill health I am happy to put my own two cents worth here.
As a newly arrived immigrant in 1995 I was pretty much gobsmacked by Finnish food culture. I started work with a good and well appreciated catering company who had a graduate of the cordon bleu school as their Chef de cuisine.The level of presentation in this company was excellent and appreciated by someone (me) who has worked in England and also the Mediterranean.
Imagine my surprise (distress) when I was introduced to the delights of the näkki kioski !! at 02.30 on aSaturday morning, the lihapiirakka was indeed designed to teach what your digestive system was designed for.
progressing from this experience to Mammi and the even more life threatening madekeiitto over a period of time I did consider moving back to Spain.
One of my worst experiences was at a much revered watering hole in Töölö, Ravintola Elite, where, they (at that time) were unable to grasp the meaning of the phrase "customer service", of this establishment I can only say i have never returned.
However there is light at the end of the tunnel, not all restaurants in Finland are crap, indeed many, in fact very many of them are excellent.
The ones to avoid in my opinion are those who overcharge for wine (we all know what it costs in Alko moreover we all know how little time and effort it takes to open the bottle,) the ones who make very pretentious statements such as "the whitebate is doused in flour then tossed fleetingly in a pan of very hot butter resulting in a mouthwatering delicacy you will be unable to resist"

, also avoid the ones who make you stand at the entrance for more than 1 minute before they decide they want your business.
Food in Finland is pretty much the same as everywhere else, you can find good and bad, on the whole you get what you pay for !!
But, what we really need here is a damn good fish'n'chip shop end of rant, sorry
