Innisfree is a skincare brand and yep they've got a cafe above their store! (This store sells pretty exclusive stuff too if I'm not wrong). Sudachi is a lime-like fruit, speciality of Tokushima in Japan, apparently only used as food flavoring in place of vinegar and not eaten as a whole. This citrus-infused cake is 6,000₩ and a delight to have, absolutely refreshing. Not cloying and we finished it, cream and all.
