Porquerolles Island is such a crowded and touristic place that it is difficult to find a nice and authentic restaurant.
We stumbled across The Auberge Glycines and were very lucky to get a table - I am told you need to book to avoid disappointment.
The setting is very charming. You eat in the courtyard of a Provençal villa, away from the busy and noisy streets nearby.
The service is very friendly.
The food is typical of the area, with fresh fish dishes. We had a reasonably priced 3 course menu with a 'carafe of rose' and enjoyed every bit of it. We were not convinced by the use of Polenta in the main courses but that was a small thing in comparison to the overall experience.
A great find.
