Most Bolivians acknowledge, when pushed, that Potosí does the best salteñas - juicy, spicy, and oh-so-tasty. Go no further than Imma Sumac, where one of these delicious items goes for around US$1; there's a courtyard space to eat in. Cheese or meat empanadas are sold around the market until early afternoon, and in the evening, street vendors sell cornmeal and cheese humitas.
