For our first evening in Rochefort-en-Terre we dined in the restaurant L'Ancolie. Ancolie (f) is French for aquilegia, or columbine. An excellent dining experience; french cuisine, generous but not excessive portions, a varied wine list (with a good selection of wines by the glass) and a charming host. We gave them a five-star review on Tripadvisor.
As an aside, the host plays classical piano, so if you have a solo instrument, he will be pleased to play Mozart, Bach, Handel with you when he's not working. Unfortunately I left my flute and sheet music at home. Another time, maybe.
Our experience of Tex Mex food in France has been limited but dismal: the only place where we ate this style of food was awful, and shut down shortly after our visit. So for lunch in Vannes the next day, we approached the Tex Mex by the town hall with some trepidation. We needn't have worried; it was great. My nachos were served with proper chopped chillis, and Anita's choice was well-prepared and presented. Excellent Tex Mex.
McDonald's was variable. We stopped in one on the way out for a quick coffee. I'm not quite sure where, but it was somewhere south and west of Rennes. They were supposed to offer service at table, but after a ten minute wait, Anita had to go to the counter to rescue our cooling coffees.
On the other hand at the Ploëmerel bypass on the way home, we ordered at the automated screen, sat down, Anita went off to the loo and the burgers arrived just after she left. I don't think I've ever been served faster.
