Els Quatre Gats

Once the lair of Barcelona's Modernista artists, Els Quatre Gats is a stunning example of the movement, inside and out, with its colourful patterned tiles, geometric brickwork and wooden fittings designed by Josep Puig i Cadafalch. The local-focused cuisine (grilled meats, rice dishes, seafood tapas) isn't as thrilling as the setting, but you can just have coffee and a croissant.
