La Cena - Dowtown, classic, continental Italian
Taverna - San Marco, rustic italian
Joseph's Pizza - Northside, classic italian & pizza
Pizza Italiano - 5 Points, classic italian
I would recommend any of these. Depending on what you're looking for ambiance wise, La Cena & Taverna are both more upscale with extensive wine lists and both ran by Owner/Chef. Joseph's is family owned and operated 2nd generation Italian/Americans, casual, family restaurant. Pizza Italiano, I've only eaten there once, but not because of the food - it was really tasty and huge portions.
While they're here, although not Italian, I would suggest Orsay for a fine dining evening, they will impress you with their flavors and service and 13 Gypsies for a tapas style mouth orgasm.
