Bar Urca On paper, Bar Urca might not sound like much – a small bar with practically no seating and a small restaurant upstairs. But in reality, this is one of the places to go in Rio on a sunny weekend afternoon. Find a spot on the long seaside wall, grab a beer and look out over Guanabara Bay. When you’re ready, get involved with the exceptional food. Don’t miss the caldo de frutos do mar.
