I went to Cafe Noriter with my friends when it was a fad way back then. I think it's a lovely place to stay, with tree house settings, you'll surely love the unique place. You could also write on post-its and paste it anywhere but as I went back there, I felt bad looking at how messy the post-its do to the cute cafe.
They serve drinks as of the moment, not much with food. They're prices are a bit high but its worth it though, with there cute glasses and big servings.
