I interview chef Òliver Peña (Rubí, 1981) before lunchtime at the restaurant he advises, Can Bo, located inside Barcelona's Grand Hotel Central (Via Laietana, 30), which has a very unusual history: the hotel had been the private residence of politician Francesc Cambó. It's a noucentista building, designed at the beginning of the 20th century, very innovative, where Cambó based his stays on the upper floors because he installed an elevator—the first in the city, I'm told at the Grand Hotel.
