予約せずに行ったところ、受付で「1時間くらいかかりますけど…」と嫌そうな顔で言われました。
こちらの店に行く場合は、予約した方が無難です。
とは言え、あんな店員さんがいる店には今後行こうと思わないですね。

When I went without making a reservation, the receptionist said with a displeased look on his face, "It will take about an hour."
If you plan to go to this store, it's safer to make a reservation.
That said, I don't think I'll ever go to a store with staff like that again.
