In fact, I thought it was such an appropriate yet catchy name to use for marketing a product especially to Japanese consumers as "Zaku-Zaku" or "Saku-saku" are onomatopoeia vocabularies that described the crunchy or crispy sounds for food. It's a uniquely Japanese thing which resonate to the Japanese who have a larger range of onomatopoeia than any other language in the world.
While this Chou-Croquant-eclair hybrid is nothing extraordinary, I think this was pretty enjoyable; a cheap street snack which I don't mind have again instead of the Harajuku crepes. The choux pastry was "Zaku-Zaku" and the cream was "Toro-toro" (smooth and glides on the palate). And it was a good thing that there was no queue at all (though I've read and heard about the horrendous queue online).
I think it's more worth trying than the soft serve (¥450), though the exclusively available at this outlet, as it's exactly the same type of soft serve sold at BAKE cheese Jiyugaoka outlet, as confirmed by the staff when I asked them about it. No surprise since Zaku Zaku is under the same Kinotoya family as Bake. It still tasted very sweet and milky, except with some extra sprinkles of "croquantes" around the edge
