There aren't many places I'd queue up for but we will make an exception for StreetXo in Madrid. We arrive at 12.45 on the top floor of El Corte Inglés (Calle Serrano 52) on Sunday lunchtime and the line is already 50 long. They started letting people at 1.30. We are waiting for more than an hour. When you are let in through the doors, it's absolutely insane. The sheer mad frenzied energy of service in full swing. It's at least three times larger than the old site we visited on our previous trip (see our earlier review here). It's a large open kitchen area with seats all the way round the counter and through glass doors a long outside eating area (where we were shown to).
