Fans of super secret decoder rings and the like may want to check out the Patron Social Club's Secret Dining Society, which masterminds dinners with celeb chefs in extravagant spaces but keeps the details (including what city the dinner will be in) to itself. For the upcoming one, the city will be announced in about seven days, and riddle will be revealed to club members, who then answer it for the possibility of getting a seat. Previous dinners include chef Marcus Samuelsson and a historic mansion in New York, and Mexican-cooking star Rick Bayless in Chicago. (Tequila people are just so much fun.) You can join for free (be sure to uncheck the we'll-swamp-you-with-email box) here.
