I'd never been to Milwaukee before, and I'd never even heard of Serbian food, but I saw this restaurant recommended on TripAdvisor and in Road Food so I stopped. Wow - it is a very understated retro (without any pretense) atmosphere with extremely friendly and personal service, and the food was fabulous. Serbian food is sort of like a cross between Greek and German (which makes sense if you look at a map of Europe). My only disappointment is that I didn't save room for dessert. I really think this is one of the best places I've ever eaten, for a combination of great local atmosphere, great food and great service.
They don't take plastic - just cash and checks, but it's well worth a stop at an ATM.
