Sardinia - Restaurant Recommendations

Hi All!

We're looking for recommendations for a few parts of our upcoming Sardinian honeymoon. We're hoping to eat locally/off the beaten path where possible.

1. Aglientu - we have three nights 2KM from the center of Aglientu. It doesn't look like there's a ton of restaurants in Aglientu itself, but we are also cautious about driving too far in the dark on potentially winding/mountain roads... Does anyone have any recommendations for eating somewhat nearby that area?
2. Bosa - We plan to eat at Sa Nassa
3. Cala Gonone - three nights here, considering Sa Cuchina and Retrovina
4. Posada - two nights, no ideas yet!

Thanks so much!

Best,
Ruth
