HEL is not so hellish! Standard EU prices really. Beer is always expensive in the Nordic region unless you drink at home where it is acceptable. But everywhere is €6 a beer now virtually. Cars can pricey.
Foot pax on the ferries can be very cheap, ($10), as it is based on "what are you going to do on a boat for 12 hours?" Eat, drink and gamble. That is how they make their money.
Overall, less than the UK I reckon but then again most places are!
