O Frade is a real time commitment — fit it in only if it's a priority.

The Alentejo countryside squeezed into a Belém corner — a U-shaped bar wrapping the open kitchen, the room dressed like a rural tavern, and clay-amphora vinho de talha (wine fermented in talhas, Roman-style) by the glass. You sit at the counter, watch a tiny team plate, and eat the kind of slow, earthy southern cooking most Belém tourists never find. Book ahead or grab a counter stool; the bar seats are the experience.
