Galeto

Located in the city's Saldanha district near Campo Pequeno, and well off the tourist trail, late-night Galeto is the nearest thing to a genuine American diner, and the original mid-60s décor is a real eye opener. The long bar snakes around the entire floor with swivel stools set alongside — great for a solitary snack. The booths, meanwhile, can seat groups of four. They've been feeding the sleepless here for nearly 50 years and it remains a celebrated comfort food destination. The brusk service will never win any prizes for finesse, and the cooking and plating up is often below par for the price paid. Still, it's worth a visit just for the experience, and simple dishes like the juicy burger and French fries will keep even the hungriest mouths fuelled till dawn.
