If the subject is restaurant food, French style cooking is standard in all Nordic restaurants above the lowest level. Before it was introduced, I guess you had more like eateries with stew and porridge, or an oven baked chicken, smoked fish and such. The French techniques have really had a huge importance for Nordic cuisines. Combined with traditional Nordic ingredients, you get something truly excellent.

It's a pity that the only food that gets international success is mostly pizza, burger, döner kebab and taco. If restaurants world wide started learning and integrating the French cuisine, they could make some great combinations with local traditions and also let local ingredients shine in a way that you can never do with a god damned burger or kebab.
