Hidden below the fabulous Kiyomi restaurant is a secret bar of whispers and stories, a speakeasy open late into the night for after-dinner escapades. Reservations are only open to those dining at Kiyomi (and can be made on arrival at the restaurant), with walk-ins left to the whims of fate. We don’t want to give too much away here, but this is one you won’t forget. There’s nothing like this in Zagreb.
