I love their Chocolate Banana Parfait. Inside this cup you'll get to taste chocolate ice cream, cream, cookie crumbs, cornflakes and banana put together. I personally feel it's the cookie crumb that makes the entire cup tastes extraordinarily delicious. Of course... it's much better to eat them all together.
I think the Taiyaki Fish Ice Cream is nothing to shout about. I mean.. it tastes almost the same, green tea ice cream with red bean in the middle covered with waffle. Nothing special, but I still love it. I just have to order this everytime I visit Zanmai.
