I work for American Eagle and Davio is just down the street. I'm convinced it's a front for the mod or something because I"ve never been able to figure this place out. They only take cash and I'm pretty sure the register is a hole in the counter.
Having said that they do a pretty good breakfast. As they say on their menu "A diner during the day, the heart of sicily at night". I have never been there at night so I can't validate that but they do a pretty good breakfast.
Bring cash...
