The Spanish love their ham. Special feed from acorns yields a different kind of flavor. The Museo del Jamón, within walking distance from the Prado Museum, was a crowded meat market/restaurant. For 8.5 euros, or about $9 US, I got a small loaf of bread, two large main dishes, a drink, and dessert. I tried my first paella, and although my friends told me it wasn't "good" paella, it was still tasty.
I also chose pollo de ajillo, garlic chicken, and surprisingly, a side of fries was included. I chose chocolate mousse for dessert, which tasted suspiciously like Jell-o chocolate pudding. After dinner coffee was an option as well. The restaurant was clean, and worth the price.
The bathrooms are down a narrow staircase. There is no handicapped access here. I doubt if any of the waitstaff are English speakers.
