These guys (81 Club Street, 9155-8374) bill themselves as Italian-Australian, and they've got some pretty good lunch sets that they encourage eating in a shared manner.
A relaxed dining space in the CBD for some hearty Italian dishes with an Australian take on it. It is best to come with a group of people to enjoy the sharing plates concept and take on a variety of dishes. I would say, a charming new addition to Club Street.
