From their website, it is said that they had a box of 4, 8 ,12 and 16. With the range of prices from ￥470 to ￥2000 ( USD 5 - 21 ). They also had many kind of flavor, and also a leopard print cake ! Uber cute!
So how does it taste ? So it's basically a sponge cake with banana flavored custard filling. The cake was so moist and soft. The filling was quite thick but you barely can't taste the banana. It was good, but not great IMHO. I still prefer the Shiroi Koibito cookies though :)
How about you guys? Have you try this tokyo banana? or have you try another yummy snack from Japan ? ( besides those green tea kit-kat :p )
