I have a Finnish colleague here in Paris and I sent her your post. Here's her reply:
Prices in Finland are almost the same as in Paris: Food in supermarkets is almost same price, gasoline is a bit cheaper (

Eating outside is more expensive in Finland, but quality of food is good. I recommend to try salmon and reindeer. Wine is more expensive in the restaurants, glass costs approximately 6 €, but beer and cocktails are cheaper than in Paris. Drinking in a bars is not that expensive if you’re used to prices in Paris
These are a few nice restaurants in the center of Helsinki, which might be worth visiting:

To which I would add: Of course, some of these comparisons are with Paris - food is probably a bit cheaper in Paris than the UK, although this can vary according to product. Drinking in bars is almost certainly more expensive in Paris than the UK but wine in restaurants is usually cheaper.
Hope this helps.
