The GZA and Prodigal Sunn hosted at club Chateau at Paris on Friday, after eating at Sugar Factory. I like these Sugar Factory poses. They look so serious, and yet they dined on mussels, mac-and-cheese pops, barbeque chicken pizza and “Ocean Blue and White Gummi goblets.” How can you look so serious while consuming Gummi goblets?
