A big GRAZIE goes out to "I Gelati di Joe" for clearing this mystery up for all of us.
For his heroic efforts in the world of gelato flavoring and clarification, I hereby award Joe my "random sign of the week." Heck, why not make it random sign of the month, for that matter. It's in Campo de' Fiori if you care to drop in. See what they give you when you ask for cream and chocolate...I'm curious. Maybe they'll get all confused and start pointing to the sign.
