ARGENTUM

 Robert Louis Stevenson described one of his Treasure Island characters thus: "His left leg was cut off close by the hip, and under the left shoulder he carried a crutch, which he managed with wonderful dexterity, hopping about upon it like a bir d. He was very tall and strong, with a face as big as a ham — plain and pale, but intelligent and smiling." The character inspired the name of an American seafood chain, which is headquartered in Kentucky and has over 1,200 units worldwide......... NAME IT...
