Housed in an imposing dark glass skyscraper intertwined with steel waves of purple and maroon and named after the Japanese-Brazilian artist, the Instituto dominates the Pinheiros skyline. It was designed by her son, Ruy Ohtake, one of Brazil's most loved and hated architects and isn't scared to shock with challenging exhibitions.
The Instituto shop, on the ground floor, is worth a look in too, stocking local handicrafts and hefty art tomes. To satisfy a caffeine craving or a rumbling tummy, the recently-opened restaurant, Santinho, filling one half of the ground floor atrium, does an excellent lunch buffet.
