Hi rherstell,
I think Logrono is a fine place to start. It's a nice small city.
And make sure to take the time to do a tapas "crawl." There are some amazing tapas places there, all crowded together on the same couple of streets. And here's what we did -- we went into one place that had been writtten up in the New York Times and we ordered their signature tapa -- it was mushroom with a little shrimp on top. At the bar, we then told the waiter that we wanted to sample the "next best" tapa in Logrono because we were only going to be there for one night. He sent us to a tortilla place that was terrific, and so we went for one or two more, one included some little crunchy ham sandwiches, etc. We found that there was no snarkiness or unwillingness to recommend the competition, I think it was their town pride that meant they wanted us to leave with a good impression of their community. (This was quite a contrast to the previous time I had been in Logrono, back in the 1970s when I was standing calmly on a street corner having just met a bunch of spanish students, when all of a sudden a police car drove up, the grises (cops in grey) came out swinging billy clubs, and we scattered as quickly as possible. Never did find out what that was all about). Buen camino! Laurie
