Isa
If you want tapas, it's the place!
Madre de Dios is a great spot with good, prompt service located on a street of the same name. If you want tapas, it's the place! It's full on weekend nights, but you can always book ahead by phone - a good choice if you want to avoid the waits. It's open every day, and all the food is good, but I recommend the fried artichokes, the sirloin steal, the goat cheese with tomato jam, and the potatoes with ham and eggs. The price with glass of wine and no dessert is around 10 euros. Worth it.
