Zenkashoin is a Japanese confectionery cafe five minutes on foot from Karasuma Oike Station, focused on fresh castella and matcha desserts. Its signature tea set, the tea garden's tea table, brings together 'Zen' castella, egg yolk honey, and a seasonal castella. Inside the shop there is a courtyard and a gallery where guests can have tea and sweets while looking at the garden. The castella has a short shelf life, so it cannot be kept for long.
