Time Out says
Set in the old boathouse of a 15th-century summer mansion, Kasar is a good choice for those who want to escape the crowds of Dubrovnik and enjoy home-made food by the sea. In fact, this restaurant is easier to find from the sea than after the ten-kilometre drive from Dubrovnik. Parking is also hard to find in Zaton, but the trip is worth it. By day, Kasar allows you a break from your swim – if you’re arriving by yacht, there are two moorings at your disposal. Rustic, home-made cuisine is based on what the sea has to offer – and your fresh tuna steak or tasty lobster will be complemented with home-made bread with olive oil.
