A few good recomendations on Loutraki.I was there on April and had a fabulous time.
For modern Greek food with deligtful flavors Rigani,very close to the Cazino,Papanikolaou 5 Loutraki 2744066744 2744021044
My other choise is Gianis by the water in the heart of Loutraki,I love the shrimp saganaki,the fish plater ,a wonderful melange of fried small fish,octapus,kalamari......
The bread in that place is amazing heavy home made bread!!!!!!!!!
and Maestrali a very popular place with the locals for meat and fish.
All of them are very popular with the locals and very very busy.
Have a good time .
