Unfortunately, I happened to be in town during a major (apparently common) thunderstorm on day #1 and a local holiday on day #2 where some sites were closed. So I didn’t get the full Santiago experience and don’t have too many recommendations. I’ll keep it short:
There is one street in the old town that is always crowded – Rúa do Franco. This is where you will find some of the best restaurants in town, known for their fresh seafood and in particular the ‘pulpo a la feria’, a classic Galician octopus dish. As you walk down the street, tanks of sea creatures will try to lure you in, and when you pick one, you won’t be disappointed. TIP: In Galicia, it is customary to receive a free tapa with your drink (like in Granada and Nerja). So you can get by on a budget and still enjoy the local food and drink!
