Best plain slice in town? Lots of people will give us flack for such a bold statement. Lucia Pizza is a well-known pizza joint that everyone loves for their no frills Sicilian or plain slice pizza. According to a local, they even have the original cash register mounted on the walls. Lucia Pizza has been around as long as we have lived in Flushing—over 20 years. The guys here are super friendly and a plain slice has the perfect thin crust, just the right amount of tomato sauce (we don't like too much of it), cheese, and oil. Grab some napkins!
