Maybe you're feeling adventurous, so you prowl the West Side Market in search of the strangest food you could possibly bring home for Saturday dinner. Or you're searching Cleveland's carnivorous emporium for the ultimate in Halloween shock value. Or you just took a wrong turn while looking for a nice, civilized half-pound of cold cuts when, suddenly, there they are, all red and toothy and staring you down. Who would eat a lamb's head? We hear there are guys from the Old World who think the eyeballs are a delicacy.
