Exhibit A: "My doorman lives across the street from Tonic in Murray Hill. Apropos of nothing, he said that is was madness there on Saturday night. Supposedly there were all kinds of crowds outside and that the cops had to be called to restore order. All this and the roof-deck isn't even open yet!"
Exhibit B: "FYI, Tonic East at 29th (I believe) and 3rd Ave. opened on Friday. Three levels, roof top bar, great food!"
