Did dine at Cabana Grille on Lakeshore a couple of times (lunch) and the food did seem somewhat adventurous though the headline chef has reportedly since moved on. Might be worth a try.

There's a restaurant at the Laughing Moon on Lakeshore (well on the way to Summerhill/St. Hubertus/Cedar Creek) that tries to be adventurous but the location seems to be bad and restaurants seem to open and close all the time. Not sure what is there now.
