Tapas 24

Tapas 24 is the most casual restaurant from El Bulli alum Carles Abellan. It serves old standbys with a gourmet twist in a bustling yet relaxed space. The no-reservation policy means there's usually a line of hungry patrons snaking onto the street, but once inside, diners can order a bottle of wine to enjoy during the wait. Menu staples are the umami-packed Bikini (a ham and cheese sandwich layered with black truffle), the McFoie Burger and xocolata amb pa oli i sal (three quenelles of chocolate mousse with a touch of salt and olive oil).
