Going through some of the reviews it become apparent you have missed much better and more decent places around Croatia that are offering this kind of meal.
First of all, place is not organised as authentic local "konoba" as they call themselves (Konoba Nikola), but is rather very simple, cheaply arranged restaurant. Decoration of the restaurant, something many highlighted, is just cheap Chinese copy and not a real stuff. i.e. you will find number of glass jars filled with peanuts on the shelves. In fish restaurant ???? What for , and what is in common except to fill empty walls?
Waiter himself seems to be very unprofessional, even it leave impression of being friendly in eyes of foreigner for whom this is first time he is coming here.
He would easily join your conversation meaning he has been listening what you are talking about. Not really professional though. Further, as someone already mentioned earlier, one of the biggest issues is the speed of the service. Like described, - as the evening progressed we had to actively "work with the staff" to accelerate the service. And it is like that indeed.
In no moment we were presented with the menu, so you MUST rely on the waiter and his recommendation. Even we ordered different, we were served else .Explanation was ,"no need, this is better" ??? Coming in restaurant, ordering for your own money ,simply it is not a right practice however friendly could sound.
No need to say that without the menu, you are unaware of the prices and as such may end unpleasantly surprised. Something that has been mentioned already in others reviews.
Regarding the wine, there is no wine list, so again have to rely on the waiter and his recommendation. As so, we ended with some, can't say a bad wine, but too fruity and "funny" (as waiter described the wine - (so much about his knowledge that has been mentioned)) that did not go well with the food I have ordered.
Regarding food itself, I must admit it is tasty and nicely done. Nothing spectacular but OK. Obviously they have good cook that is creative in his work and have sense for his work and costumers expectations at this type of the restaurant.
But issues as described above ruins your feeling of the night because of which I give only 3 stars.
Would I come back, probably not as there are many other places with better service that is main issue of this restaurant.
If you prefer organised restaurant with professional service / staff this is definitely not a right place for you.
