Dominique Ansel created a storm the last time he showed up in town, with hundreds lined up to try his cronut at Barneys New York at the Grove last March. Tonight, he´s bringing his signature cookie shot along for the ride during his book tour, which takes place inside the three-story Barnes & Noble inside the Grove. The madness starts at 7 p.m., though the Twitter excitement seems to indicate that a long line will likely form early on.
