I visited this pub a few times while in Madrid. I watched a few of the Rugby World Cup games here as well. A crazy atmosphere whether you visit during the day or at night. Not much of a beer selection but the Guiness pours nicely and flows all night. There is an upstairs and a downstairs bar that seem to be packed all the time. And on weekends they usually have a band that kicks off around mindnight, the bar stays open until 4 or 5 A.M. so you better have plenty of plata and stamina to carry on into the morning.
