I don't know. It seems like every single thing I eat from a patisseries is perfection personified. At Marimo, there was this cake with a cream with a very unique texture. The pies are awesome as well; what I found most unique was the tiramisu daifuku. Fun! As for the butter cookies, they tasted good, but they always do, no matter where I buy them from.
You'll see the patisserie; sometimes he's even the one selling stuff. The only other employee is a female, maybe his wife. Kind people; used to dealing with some foreigners. Not a bad place to hit up.
