Buneido

The moist sponge and crunchy sugar at the base are defining features of castella at Buneido. Reviewers describe the sweetness as restrained, with the sugar adding a pleasant textural contrast. It’s an appealing choice for a simple sweet treat, or for anyone who particularly enjoys that crunchy finish.

There’s more than one variety, including versions with and without honey, as well as one made with liqueur. You could start with the sugar-bottomed classic, often mentioned as the standard choice, then take home another variety to compare. Takeaway is available, and some customers have chosen the cakes as gifts. If you’re settling in at home with a pot of tea, choosing a drink to go with your castella can be part of the pleasure.

There is no dine-in option, so the cakes are for enjoying elsewhere. One reviewer bought castella offcuts and was able to try two flavours—a useful idea if you’re undecided.
