Maybe not the best, but certainly the most interesting. Sitting in Il Mulino in NYC with my wife. We were at the bar by the window waiting for a table. Just finished a Belvedere Martini (yes, the vodka kind) when a guy at the bar starts a conversation with us. He then asks us what we were drinking and I told him. He started to smile, and told me that I had answered the question perfectly and that he would buy me our next round of drinks as he OWNED Belvedere Vodka. He was there taking a good client out for dinner. Gave me his card, and we had a great conversation with he and his guests.
Not much longer afterwards, I read in Forbes that they (he and his son) had sold Belvedere for some ungodly sum of money. Cheers!
