Nisiotiko fish restaurant is for sure the place that i choose for the freshiest fishes ever. Kyriakos, the owner, is a friendly guy that knows very well how a very fresh fish is cooked. A great variety of other seafood plates , delicious fresh salads and some great wines will help you have the best food experience. Prices are equal to the quality you are having.
My place is 300km away , but when i get the chance and visit Alexandroupoli i am visiting Nisiotiko every time.
