If you end up going to Beaune then just to the north there is Aloxe Corton. A great red and also home to Corton Charlemagne white. I bought a case many years ago while on honeymoon so thought I'd check prices today... even at the online discounters nothing is under the $100 mark and most much more than that. Hate to think what the restaurant price would be! I don't remember it being very expensive at the Chateau but of course it may be much more popular now than back then.

Think I'll have to go there next year on my annual car trip down to Spain.
