Bilbao Sunday lunch - Mina, Porrue, ?
Looking for a memorable Sunday lunch in Bilbao. Maybe one of the two listed in the title, but we are open to other suggestions. Prefer a place within walking distance of the Guggenheim (close to our hotel).
Mina is about as far as we'd want to walk, but if there's something really good outside town we could take a cab. I know Azurmendi is open Sunday but we are already going there on Tuesday.
I couldn't find much on either Mina or Porrue here on CH. Anyone familiar with either of these, or something similar you might recommend?
