Sister restaurant to the excellent Nautika, the seafood-oriented Proto claims a tradition dating back to 1886. And it was here that Edward VIII entertained Wallis Simpson in the 1930s. As well as squid and lobster in simple, superbly balanced sauces, there’s fresh shellfish from Ston up the coast. You can spend an enjoyable hour over the fish platter for two, and the extensive wine list covers just about every quality wine that Croatia has to offer. Choose between restrained elegance in the 1930s-influenced dining room, or Old Town views from the first-floor terrace. Booking essential.
