I was being a smartass about the food but I certainly didn't know Hemingway and his crew hung out there, that's cool (I saw Midnight in Paris recently so Hemingway is sorta fresh in my mind)It was the original Sloppy Joe's Bar. Hemingway and his crowd ate and drank there. The food, you can guess.
Have you HAD Sloppy Joe's before? Seeing as you're an English bird - I don't imagine mince with ketchup on bread would be all that popular over there, though I guess it might be like having spag bol on bread (minus the spag)?
