If you want to get a feel for Old World Madrid, its food and atmosphere, this is the place to go. Originally built in the 17th Century, Posada de la Villa looks like an old Spanish inn. It features many traditional dishes, but their specialty is the Roasted Baby Lamb. In addition to its old-time feel, it is noted as being one of the more famous bars in Madrid. Not only that, but it is so close to the Plaza Mayor that you'd be a fool not to make a visit. Enjoy!
