La Fontana De Oro is Spanish for the golden fountain. I don't know if they are hinting at leprechauns and their pots of gold because it's a strange name for an Irish bar. It's situated between Plaza Del Sol and Plaza Santa Ana, an area of many bars of this ilk where you can easily meet and mingle with drunk foreigners. Although an irish bar, La Fontana De Oro is not a traditional pub but a place you really feel at home being plastered, dancing and making a fool of yourself. It's open til 6pm every night of the week, so there's plenty time for it.
The upstairs is a very large room on split levels with two separate bars. The bar on the right has seats whereas the lower one has high tables for resting your beer. At the entrance there's a dance floor
and a stage for live music raised a couple of meters above. Check out their website for the latest bands.
Downstairs you'll find a strange medieval look. There are wooden tables with large throne like seats. It's a great place to go for a more civilised chat away from the rowdiness above. Down here you'll also find a little private room with a pool table. It can be a little difficult to get game because it's one of the few bars that has a pool table in Madrid.
