Met up with Scott, Michael Osman's partner, outside of the Hotel Chopin (which is conveniently located around the corner from Chartier)
so that we could have dinner with D & L, the lovely couple from NYC that I met the night before at Jim Hayne's dinner party.

He is worth at least 3 times what he charges!!
