Calvi and La Balagne, Corsica....recs
Have you searched the board for Corsica recommendations? It's worth doing, as there are a few posts on the island.
Here's a copy of a recommendation I made a couple of years ago - the prices will be out of date now though:
It's a drive from Calvi, but the Augerge de Tesa is lovely. We stopped there for a meal and a night's stay on a whim a couple of years ago, and had a very memorable meal. It's excellent value - they only have a five course set no choice menu (although you get a choices for the main course). It's 38 Euros for the meal, including aperitifs, all the wine you want, digestifs and coffee. The rooms are also good value. It's location is idyllic - very rural and next to a stream with ducks, peacocks and willow trees.
It is inland from Lozari, which is just North of Ile Rousse - I'm not sure if that is too far for you, but it is worth the journey.
I went to Calvi in 2005... It was lovely. Unfortunately, I didn't keep good notes and can't remember restaurant names... there was a terrific fish restaurant in the marina.
Do you read French? I suggest getting a Guide Routarde for Corsica (Corse). I found their restaurant suggestions particularly good. Even if you don't speak French, I bet you could decipher the info you need.
