We did not eat at Fialho when we were there in January. Instead, we chose
Dom Joaquim which is a bib gourmand Michelin restaurant. It is a short distance within the city walls. It is somewhat rustic food, and it hit the spot for us that particular day. We had a pork pie that was awesome. They put a number of plates of small dishes on the table. If you eat them, you are charged. You don't need to eat any of them. We would return.
