They sell typical Brazilian snacks but are really famous for their pão de queijo, Brazilian cheese breads, which are good but not exceptionally good.

The pão de queijo is as good as everyone says - as are the other snacks and the espresso. And they're friendly - although sadly the same can't be said for some of their up-market clientele.
It's a little bit pricely but a nice Pao de Queijo near here! Good expresso!
