For a century and a half, the building housing Guixot has taken on many personalities – though one thing has remained the same: It’s always housed some type of bar that also served food. Now a tapas bar celebrated for its sandwiches, brothers, partners and cheery owners Francisco and José Gutiérrez Murillo have been running the iconic eatery in the Raval neighborhood since 1986. Here we can find some of the more interesting sandwiches of the Old City, along with good tapas and a lunch menu of daily specials. Exuding a relaxed, familiar and friendly atmosphere, the space still keeps an old school look with its marble tables and thin iron columns from the past century dotting the interior. It makes good use of its walls, exhibiting paintings that seem to recall its previous life – and it’s had many.

It all started with a seriously delicious hamburger in New York City. Rumor has it that it was this burger that first gave acclaimed Catalan chef Oriol Rovira the idea of opening Sagàs Pagesos y Cuiners (“Farmers and Cooks”) in the Born district of Barcelona. Specializing in high-end sandwiches, the restaurant embraces the farm-to-table philosophy, with a menu that is both distinctively Catalan and international in scope. Rovira, who also runs Els Casals, a Michelin-starred restaurant in the tiny village of Sagàs near the edge of the Pyrenees, opened his sandwich spot in May 2011. As at Els Casals, nearly all of the food at the Barcelona venue comes straight from the chef’s village farm. But why sandwiches?

Between two simple slices of bread exists a mind-boggling array of possibilities – something not lost on Spaniards, who have turned sandwich making into something of an art form. In Spain, sandwiches go by different names depending on the kind of bread used and local custom. The type that’s generally called a bocadillo in Spanish and entrepà in Catalan traditionally comes on pan de barra, itself a broad category of bread, with varying dimensions, qualities and more specific names, including baguette, maybe chapata (ciabatta), depending on how round the bakery makes it, pistola (pistol) in Madrid and flautas (flutes) in Barcelona if it’s short and very thin.

Not far from the Gràcia neighborhood’s glittering Paseo de Gràcia can be found a completely different world of narrow, unassuming side streets. Once populated by Catalan Gypsies, the area is fondly remembered as one of the cradles of rumba catalana, a popular fusion of flamenco, mambo and rock and roll, and as the birthplace of Antonio “El Pescaílla” González, a legendary flamenco guitarist who was one of the genre’s founding fathers.

The large banner in La Nena chocolatería proclaiming “No Hay Alcohol” (strung up between a rocking horse and a wooden toy kitchen) makes it fairly clear that this is not a place for sophisticated conversation and cocktails. That doesn’t mean that La Nena (which means “The Girl” in Catalan) doesn’t cater to any other vices. Indeed, its delicious homemade cakes, pastries, hot chocolates and savory snacks tempt the residents of Barcelona’s Gràcia neighborhood on a daily basis.

Can Paixano, the kind of timeless dive that could soon be extinct due to the rise of Western chains, is an obligatory stop for anyone wanting to taste a slice of the real Barcelona. And the bar’s location in Barceloneta, the traditional fishermen’s quarter where the old port meets the beach, provides the perfect setting.
