I saw those little things at another tapas counter recently, wondering what they heck they were. I figured that they were either clams (I hoped) or maybe some beans. So I got some here, and it turned out to be the latter: lima beans, I believe. Anyway, this was just an old tapas place that I went to out of convenience (9 Avenida del Regne de València, +34-963-746-525). Nothing got me that excited, but it was fast and friendly, and I got some morcilla de arroz blood sausages while I was at it.
