Katherine <3: lots of Diego Rivera and his contemporaries. Look for the hairless dogs running around. They are called Xoloitzcuintle (squinkly)
Katherine <3: Beautiful residential neighborhood, good contemporary exhibits. Mom and I saw an Andres Serrano show that knocked my socks off.
Mark: Skip the line for the observation deck and go up to the bar on the 37th? 40th? floor.
