Just off the bustling main street of Rio’s busy commercial centre is a small, nondescript shopping mall that is home to one of the city’s best coffees. Taking over the end of a corridor, the most notable features of Curto Cafe are the distinct lack of cashiers and price menu. That’s because the customer only pays what they want to pay. The owners write the shop’s expenses on the wall and calculate a sustainable price to keep the coffee shop running. There are only three products on the menu – cappuccino, espresso, and coffee beans – which allows the baristas to perfect the offering quality. The cappuccino is deliciously smooth and creamy, and the espresso has a mild, nutty flavour.
