Porta 4

Tapas in Miragaia

The clue's in the name: Porta 4 has just four tables for a lucky handful of diners, so book ahead. If you can snag one of them, you're in for a treat: this enticingly cosy cubbyhole turns out bang-on-the-money petiscos (tapas), from squid with green apple and basil to pork loin with beetroot polenta – all at €5 a pop.
