We tested several types of pinchos (which are bigger than a tapa) and they were delicious! Prices vary, they cost € 2 or so, but they are generous portions! We had four each and when we left we were stuffed!
The bar is modern, so do not expect something rustic, but we liked it! And there are many people, as in all bars, so you have to have a little patience. We recommend the chorizo skewer. Great cider!
