A genuine Santa Teresa institution, small, cosy and nicely decorated, Arnaudo's has been serving good, reasonably priced food for over forty years. Northeastern cuisine dominates the menu, and the carne do sol (sun-dried beef,) feijao de corda (brown beans with herbs) and, cholestoral levels allowing, manteiga de garrafa (ready-to-pour melted butter in a bottle), mean it is literally one restaurant not for the faint of heart.
