At the harbor the view towards the beautiful, green sea and the fishing boats is a sight. Here yoy can speak with a local tanned fisherman who sorts out fish or repairs his fishing net.
Most of the restaurants close to the sea are very touristic and not so charming. If you would like to have better food in nicer locations, I recomend to find a restaurant in one of the side streets or in the square behind the harbor. Here the atmosphere is more greek. Have a pink gin at the inspiring Pergamonto! Close to Pergamonto you´ll also find the restaurant To Tigani, which at least served me one of the best greek meals I´ve ever had. Sit outside! Unpretentiously atmosphere, homemade food and with a very present hostess.
We was recomended to select a mix of their favourites on the menu and got big trays on the table which everyone shared. Fried sardines, calarmaris, whole barbequed fish, huge shrimps, filled mushroom, meat, squasballs, fried aubergine, olives, feta....
There are many shops in Pythagorion -most of them are what you´ll probably expect for a touristic small city, but you can also find some nice ones selling linnen, straw hats, dresses and ceramics.
If you have time I´ll suggest that you take a daytrip to a hidden beach with one of the tourist boats located in the harbor. You´ll have food during the day, have a swim in the greenest water ever and it´s nice to see Samos from the water side too. It´s absolutely worth the money.
Pythagorion and Samos have a calm and lovely atmosphere all over. Maybe not completely Mamma Mia but still a place I would like to revisit.
