Hi, musicagl,
I second the opinion on Logrono. If you have time to sample the tapas, there are many outstanding places to do that. I remember some amazing tortilla, some amazing peppers, and some tiny little shrimp on top of a mushroom that were yummy. Here's how we navigated the maze of tapas (and we did this in places like Leon and Pamplona too). We found one tapas place that looked crowded and good, went in and had something, and then we said to the person waiting on us -- this was great, we would now like to sample another equally excellent tapa, can you suggest where we should go? We explained that we were only in the town for one night, walking the Camino, etc, and wanting to get a "feel" for the place, and we found without exception that the people we asked were always happy to point us to the "second best" tapas place in town. We really sampled some excellent food, which was always extremely welcome after the relentless drudgery of the menu del peregrino.
My other consistently good source of information is in farmacias. I don't know why, but whenever I'm looking for a place to stay, a place to eat, a place to buy something, I ask in the pharmacy and they always give me a good answer. In fact, on the Vdlp this spring, I went into a pharmacy to ask if they knew where any internet cafes were, and the pharmacist insisted I go to the back of his store and use his computer and internet!
Buen Camino, Laurie
