The clock is ticking for those who want to taste molecular gastronomy pioneer and chef Wylie Dufresne's New York City-based restaurant wd~50. Today on Twitter, Dufresne dropped the shutter bomb: "Nov 30 will be our final night of service at wd50. Come celebrate with us for the next 173 days. Stay tuned!!" Though it's not a complete surprise, as Eater NY notes, since the building is set to be razed. No word yet from Dufresne's camp on whether wd~50 will reopen in a new location or is gone for good.
