summer vacation!

I go to FINLAND in summer.
I'd like to go moomin museum,marimekko shop and more.
I'd like to eat many Finnish dish.
Please teach me,your recommended cafe:)

This is generally good and I can understand everything. You can make it better.

I'm going to Finland in the Summer - 'going to' is used for future plans

I'd like to go to the Moomin Museum, the Marimekko shop and more - 'the' is often used for place names when there is only one of them. Place names start with a capital (big) letter.

I'd like to eat many finnish dishes - finnish here is an adjective so does not have a capital letter. Dish should be plural here.

Can you recommend any cafes for me? - Make this into a question, it is better.

Well done
