You are learning bread and sweets: you will read the scene it happens in, learn 10 words and phrases, take apart the pattern behind them (arimasu ka + bread and sweet shop vocabulary), hear them in a conversation, rehearse them, and finish by saying one thing out loud to be graded.
A depachika (department store basement food hall) in Shinjuku or Ginza. The most extraordinary food environment in the world — hundreds of stalls selling pastries, wagashi (traditional sweets), melon pan, and matcha everything.
The basement food hall at Isetan Shinjuku has over 400 stalls on two levels. The stranger has been walking through it for forty minutes and has bought nothing because choosing is difficult and everything looks extraordinary.
Finally: a wagashi stall. The seasonal sweet — a delicate mochi in the shape of a maple leaf, filled with chestnut cream — is labeled "限定品" (genteiban — limited edition). 「これはありますか？」 pointing at the label. The staff nods. 「はい、でも今日で終わりです。」 Yes, but today is the last day.
「三つください。」 Three please. The woman wraps them with origami-like precision in paper, then a box, then a bag. The whole process takes two minutes and twenty seconds for a ¥1,200 purchase.
This is the depachika. Every transaction is conducted as if it were the most important one of the day.
