Flash Flash opened in 1970 and became an instant Barcelona institution — a sleek white room with mod decor that has barely changed since. The menu is built around the tortilla, with dozens of variations from the traditional potato-and-egg to more inventive combinations. Reliable burgers too.
It sits on a quiet street in the upper Gràcia district, popular with a local crowd who have been coming for decades. The look is unmistakably of its era, which is exactly what people love about it.
