OK, can't take it any longer, been many years since I was there but I'll presume the strip malls haven't fully marched over the core.
Start out around the forks, lots going on there kind of a tourist spot. Some good food but places tend to come and go there so I'm adverse to naming names.
You can consider the Osborne Village. Carlos and Murphy's is a place for semi-Mexi and then down the street to Baked Expectations for dessert.
The Exchange district has some bars and upscale restaurants but some people don't like that hood after dark.
Also you can head down Corydon for a bit of an Italian vibe.
