Piscolabis

This is all about what you order. We ordered from the «standard» menu and got salads and calamari and pork. Both were good — not great. Others in the group did not enjoy theirs — but they did not try to get local cuisine. Service was good. On a do over, I’d try something off of the main plaza.

Situated in the plaza, along with about 15 other seemingly similar restaurants, Piscolabis has ample outside seating and a few tables indoors as well.
They have the standard menu del dia for lunch (a primo and secondi, along with sangria or wine or beer and a postre (dessert)) for around 10 euro. They also have lots of tapas that can be ordered a la carta.
If you are vegetarian, you’ll be fine. They have a pretty decent number of things for you — the spinach fajita stands out as an interesting option, featuring thick rounds of a local goat cheese along with quince paste (membrillo) atop flour tortillas.
Now, if you’re vegan like me… I just hope you like gazpacho. Fortunately, I love it, which is good because I lived on it for about 10 days. The variety served by Piscolabis is quite good (make sure to ask for it «sin jamon» aka with out ham) and the portion is enormous.
I also tried their mushroom risotto and a delicious carpaccio of garlicky eggplant. I’m sure it didn’t hurt that I was accompanied by a colleague who is a native Catalan and person friend of the owner, but they were very accommodating to my special requests for this or that. YMMV.

Buena cerveza y el precio nada mal.
