If anything in recent history has bonded Spanish hearts, it was neither politics, language, flags nor even TV. It was the tortilla de patatas, the iconic potato omelet. In every house, bar and restaurant, the tortilla de patates is always treated with intimacy and respect, like some sort of communal great-great-grandmother. And in every Spanish city, you will find a list of the best kitchens offering this specialty. For Barcelona, one neighborhood temple devoted to the omelet is Les Truites, a small family restaurant in Sant Gervasi run by Joan Antoni Miró and his son Marc.
