I paid a visit to that nice little shop as well, but unfortunately I didn't meet Luc as he was out and wasn't to return until the day we left for Bayeux.
Funny thing too... we had walked there all the way from the area of the Louvre, and the tiny shop had been quiet all day of course until the minute we showed up. It was hard to get around and have a good look, and one of the people who followed us in seemed to be buying out the contents of the store.
I also made it out to Cantada II, where the fountain they serve from looked more like a bong or some sort of science apparatus. The water wasn't cold (no ice was used) and the bar man liked to serve the absinthe 1:1, but other than that...
Glad you had a good time. Fortunately for me, I don't have to think about work until Monday.
