After dinner, Martin was very kind and took us on a tour of the wine cellar. We entered a temperature-controlled room lined floor-to-ceiling with wine-packed shelves on each wall. A grand table sat in the center-- I assumed this was a VIP private dining area. I made my way around the perimeter, marveling at all the Sauternes. Then, he opened a door and led us into another room-- filled very much in the same way with wine, a long banquet table, and with several glass cabinets housing and showcasing particularly amazing bottles (including what appeared at first glance to be a complete vertical of the Mouton Rothschild artist series); ok I figured, this must be the VIP private dining room and the real cellar.
He opened one more door and led us into the real real cellar. This was an extremely large underground room, very dark and cave-like with wrap-around perimeter shelving and library-style shelves spaced throughout the room in rows about 3 feet apart. Here all the bottles were sleeping. It was pretty overwhelming being there-- each bin filled with incredibly amazing wines. We left in a dreamy daze.
As a side note, we had this incredible dessert: simple, sweet milk-soaked bread with vanilla ice cream. It doesn't look that impressive from the photo, but it was so delicious, I'm still dreaming about it.
