Nomiya, an art-meets-food installation on top of Paris’s Palais de Tokyo, is one hot ticket. My sister-in-law, Yuko, had Jeopardy-button-pushing dexterity in order to secure this lunch reservation from—of all places—eBay. Availability was gone in less than a minute. Meant to be a temporary exhibit by French artist Laurent Grasso (hence the “limited-time fever”), it has been extended indefinitely: 12 strangers dining at one intimate table dangling above the Seine. It is most certainly more stunning at night, when Paris is illuminated beneath, but lunch had its artistic intrigue as well.
