At the Sunshine City Mall in the Tokyo Ikebukuro area of Japan, you will find the lovely Maison Kayser Bakery. Located on the 1st floor (1F).
With the option to dine in or takeaway, I chose takeaway since it was one of our last stops before boarding our flight home. 
So many sweet and savory options to choose from but I had my heart set in the Croissant Palmier. Available in 3 flavors.
I choose the Pistachio with White Chocolate and the Hazelnut with Dark Chocolate. Only 580 yen each which converts to $3.90 USD.
I love the thin layer of sugar on top of the croissant adding extra texture to the flaky dessert. 
You should definitely try it, 10/10. I want to go back and load up on more of the savory options!
