Have you tried Iron Beer? Have you even heard of it? It is a soft drink that originated in Cuba (in 1917 according to Wikipedia) which might be why the only place I've ever seen it is Miami. It kind of doesn't make any difference to me that I can't seem to get it anyplace else because, though very delicious (I'm not even sure how to describe it...a far yummier version of Dr. Pepper, maybe?), I don't think I want to have it any other time than when I visit Key Largo. After coming in from a long, hot day at the beach, nothing really quenches your thirst quite like it.
