Restaurant The Star

For those who are serious about Portuguese street food, Astro is a place of pilgrimage. Located right in front of Campanh Train Station, this no-frills snack bar is widely considered by locals and in-the-know travelers to serve the best bifana in Porto—perhaps in all of Portugal.

The bifana here is deceptively simple: tender, marinated pork, cooked with a subtle touch of spice and stacked on a soft bun. It is juicy, tasty and best enjoyed in classic Porto style: accompanied by a cold beer and a bowl of caldo verde (traditional cabbage soup). A popular food writer admits to returning several times just to confirm it really is the best—and consistently delivers.
