"Can Martí is a very informal restaurant in the mountains, best accessed by a hike along the Carretera de las Aigües, a dirt road where people from Barcelona go to jog, bike, and walk their dogs. Accordingly, it offers great views of the city. The food is simple, with dishes like tortilla de patata, judías blancas, barbequed meat, salads, and barbequed calçots. It’s essential to reserve in advance, and if it’s calçot season, reserve those, too."
