Kokoo (meaning “contructs”), what a great place for the whole family on a grey day with sleet coming from the sky. It has a simple concept: go in and use the big supply of legos, and build!
If you want to you can buy the Lego per kilo once you’ve built something but you don’t have to. Entrance fee is 9e for dad and a child or 5e/child (adult company for kids under 8 mandatory), and there is loads of legos to play with (while mum goes shopping, which equals fantastic for the *whole* family).
Kokoo is in the middle of Forum, couldn’t be more central in Turku. (Nice to know: the Legos are desinfected regulary).
Dads (and mums who like Lego), you need to go there, build and have fun with your kids!
