Went there during our stay on sardinia - during off season time. We were welcomed friendly and got to choose our table were we had terrific view on tavolara. Altogether the food was delicious and the service was very mindfull - we thought the dessert was outstanding.
Service was fluent in English, German and of course Italian.
But go there and see for your self we do recommend it!
