About
Ten years after the opening of Il Borgo at the Castle of St. Georgiou, the beloved restaurant team has launched a new venture, bringing together the essence of Italian charm and finesse.
The menu at Osteria beautifully blends Kefalonian, Ionian, and Italian cuisines, continuing the harmonious fusion that has flourished for years in Kefalonia and throughout the Ionian Sea.




Pasta with classic recipes, quality raw materials and pizzas with 48-hour slow-ripening dough with sourdough that gives an "airy" and light result.
The fully renovated restaurant space offers a pleasant experience where you can enrich your dining experience with an uninterrupted view of Kefalonia's western side.

The carbonara was an absolute standout—rich, creamy, and perfectly seasoned with just the right balance of pancetta and pecorino.
We also had a chilled glass of rosé moschofilero wine—light, fruity, and incredibly refreshing. It paired beautifully with the pasta and elevated the whole dining experience. Also the view was great! It’s recommended for sure! read less – 10/06/25e. d.Καταπληκτικό ιταλικό εστιατόριο. Το φαγητό εξαιρετικό και το προσωπικό ευγενικό και φιλικό.

Πηγαίνουμε εδώ και δύο Σάββατα από τη στιγμή που το «ανακαλύψαμε» μαζί με τα παιδιά μας και είμαστε πολύ ικανοποιημένοι όλοι και κυρίως ο σύζυγος,που είναι και αρκετά απαιτητικός με το φαγητό. Έχουμε επισκεφθεί αρκετές φορές και το il borgo στο Κάστρο και ήμασταν σίγουροι για την επιτυχία!! read less – 10/06/25

Niente da aggiungere. Inoltre il servizio è ottimo, gentilissimi i camerieri , il locale è molto carino ed è un bel mix fra informale e raffinato. Assolutamente consigliato! read less – 10/06/25

Lovely view while you eat as it is up a hill and easy parking. They took us with no reservation around 8pm on a Friday night.
We found the price to be very reasonable for the quality. We ended up taking some home as the portions were a good size. read less – 07/06/25S. H.Great views of the sea and runway, and great food! – 29/05/25
