"The jewel of Larry Gagosian's gallery empire is a gargantuan, museum-standard center in Chelsea: The space alone is worth a visit for its sheer monumentality. And fittingly, the stable of artists displayed there consists of the art world's heavyweights from Ed Ruscha, to Taryn Simon and Jeff Koons. There are multiple outposts in the city (including a second location on 21st street) along with galleries around the world."
