Without a doubt, pintxos are one of the most typical delicacies of Euskal Herria. They come in all shapes, flavors and colors, there are practically no rules in their making.
In Lekeitio, a small town in Biscay, one of the best places to eat pintxos is in the Lumentxa tavern. It is a small place but with great variety and the best ham in town.
You can eat there pintxos and delicious sandwiches. They also have a good wine cellar from La Rioja.
The service is great, very nice waiters, but you have to take into account that at some hours of the day the place is so full that the waiters can be a bit stressed.
