In Bajardo all restaurants are very good and it is not easy to say which one is the best.
The village is within walking distance (1,50 km, 12 minutes walking) from our B&B. You can walk there and have a nice stroll back under the moonlight.
Prices are very reasonable and you will taste the ligurian specialties like the wild boar, roasted or stewed, hare "alla cacciatora" or "ravioli", the italian stuffed pasta.
Bon appetit!
