I've driven by many times, and finally stopped yesterday to take a look. I didn't have time to stay, but was suprised by how relatively swanky the place looked inside, and I was espeically impressed by the large, serene and shady outdoor seating area. The menu has a clear slant toward middle European classics, with some ecclectic things thrown in (grilled sloppy joe stuffed with cheese, anyone?), and plenty of offal offerings.
Menu:

There's a butcher shop/ Bosnian market attached to the restaurant, and that looked pretty interesting too.
Anyway, I'm intrigued and will stop in for a meal in the next couple of weeks, but thought I'd see if anyone with experience might have suggestions before I do.
