Considering the Holiday Club Oulu Eden in Oulu?

Have a lazy evening by gubbi1
Well, hard to categorize nightlife in Oulu, a town which in summer has light through the whole night. No, but seriously. In case you want to spend a relaxing evening, you can stop by Kauppatorin kahvilamakasiinit, which is in one of the old harbour houses. Sitting there and watching the people is the perfect escape from a working day.
The website below is Finnish only, but might give you an impression of the place. Have a look at the Gallery.
