"Curry/stew is a drink."

— Yuyuko, Saber, Akagi, Hana, Oguri.

Edit: I... think we need a patissier to help tag this. Not sure what that pastry with the 'grapes' are called. Knew I encountered that word before but can't remember it now. Don't think it's a mille-feuille either because of how the layers look.

(Though maybe it could be a specific subtype?)

I see you found it.

And yeah, that cake is bugging me as well, but short of asking Hisahiko himself...
