At Fish - a Boisonnerie the waitress suggested a glass of white wine to go with my mussels. It was fantastic. It cost 6Euro for the glass, she apologized that it was the most expensive. I was sleep deprived and overly excited and pretty ignorant of wines anyway. It seems that there was a "C" involved, maybe something like Cassay?
Sorry to ask such a ridiculous question, but does anyone have any ideas what it might have been?
