Los Primos ... is the name of a local restaurant that we enjoy. They also call themselves the El Salvador, which is sometimes confusing. We always thought that the name meant (in Spanish) “The Best”, or something along those lines, because “primos” sounds to us like “prime” or something closely akin. As they serve the best Mexican food in town, this seemed completely appropriate.
But recently we discovered that “los primos” actually means “the cousins”. It seems that three cousins started both the restaurant and the related grocery. Nothing wrong with “the cousins” as a name, but it doesn't have quite the same cachet for us as “the best”! :)
