Emilio's menu said explicitly "European Spanish Food". My theory was that they meant to rule out the foods of Ceuta and Melilla. A quick search suggests that Ceutans focus on fish with couscous.
Melillans seem to eat a larger variety of things (although that could just reflect the research effort put into these summaries), including foods of the Hebrew community like "the so-called coloured omelette, with its yellow egg, green peas, orange carrot and white mashed potato". (I'm not sure what the "Hebrew biscuits" referred to in the next paragraph are.)
Also, there's an Indian community: the only dish described of theirs is the samosa. (Someday I hope to understand how this particular dish, of all the myriad foods of South Asia, has achieved such iconic status.)
