We went to La Bola for dinner our last night in Madrid. La Bola has been in business since 1870 and has retained its unique dishes from that time. We ordered the beef stew with garbanzo beans.
The meal was great, but I ate far too much and was in pain later. Spaniards, though mostly skinny, seem to eat much larger portions than I am used to.
Our server was really good. This is especially noteworthy in light of Spanish customer service being consistently horrible.
