Peluquería Luis Martín is one of Madrid’s last remaining vintage barbers. It survived the frontline of the Spanish Civil war, the requisition of its beautiful chairs, and the untimely death of Don Luís Martín himself. Yet, 93 years later, and still having never given in to the hipster beard, this niche men’s hairdresser’s is still going strong.

One of the best things about this accidentally retro bar is how much fun it is to explore. There are secret, time-bending portals connecting the endless labyrinth of dining rooms… or so it seems. When the same short, middle-aged waiter in a waistcoat kept appearing every time we entered a new room, we wondered how else he could have got there so quickly.
