Calamari sandwich

Squid sandwich or bocadillo de calamares in Spanish, bocata calamares in Cheli, is a culinary specialty very common in Spain consisting of a bocadillo sandwich of squid battered in flour and fried in oil that is usually olive, or the more sophisticated version that is all of the above plus a spicy tomato sauce and mayonnaise with garlic similar to that of patatas bravas. It is usually served hot and freshly made. This type of sandwich (specifically the original version without sauce) is very popular in Madrid and can be found in most of the bars of the Spanish capital, particularly in the Plaza Mayor as well as the Calle de Botoneras at the southeast corner of Plaza Mayor.
