It is worth noting that in the Basque Country tapas are called pintxos. I think one of the only places where you are allowed to just eat pintxos is San Sebastian. San Sebastian is the mecca of pintxos and renowned worldwide for its culinary excellence. In fact, aside from Kyoto, San Sebastian has the largest concentration of michellin star restaurants in the world. You can read more about San Sebastian on my 7 Day Basque Country Itinerary blog post.
