"In 1987, Quim Márquez set up his tapas shop at La Boqueria, Barcelona's famed food market. His space was a three meter-long counter with five stools. El Quim's following grew exponentially in the next decade—and in 2000, it moved to a 16 meter-long counter with 18 stools. Absolutely stop here for an egg breakfast (with ham or foie gras, mushrooms, prawns, squid, etc.) before perusing La Boqueria. As super foodie Phil Rosenthal, creator of Everybody Loves Raymond, says, it's the kid of meal that will call you back to Barcelona."
