We first came across Nautika when we visited Dubrovnik on a day excursion in 2016, and were very upset to not have booked ahead to get a table!
We came back to visit Dubrovnik again this year and booked the table almost straight after our flights.
The restaurant does not disappoint - I had the beef main and chocolate dessert, both complemented with a wine recommended by our fantastic waiter (I think his name was Doug).
The food was absolutely gorgeous in both presentation and taste, and the service was exceptional - we were not rushed at all but also not left waiting at any point.
I highly recommend sitting along the wall of you can, where you have a lovely view across the sea... also, book ahead!
We will be visiting again :)
