This is a place where it helps to know the rules. When you arrive, walk straight to the back and pick out the fish you want from the menu and/or the case in front of you. It was early in the evening, but they were inexplicably running out of several items, so at the suggestion of the waitress, I ended up with a large piece of Swordfish, a medium sized Mackerel, and several small Sardines.Everything is cooked in the same grilled with oil and garlic style, but no one should complain about that, The swordfish (which was what would often be considered a full dinner portion by itself), was spectacularly good. The Mackerel was also quite delicious. As for the Sardines, well, I don't think I'm a fan of that species. But overall the meal was excellent, and my total bill, including a nice cup of chicken soup before the fish arrived, and a half liter of the house wine, came out a total of euros!
