To quote from this post http://tastyburgher.com/2006/09/29/jozsa-corner/:
"Need an adventure? A new place with new food? A restaurant completely like any other in the whole of Pittsburgh? Well you've hit right upon it! Jozsa Corner is a tiny Hungarian restaurant in Hazelwood and is at the very tip top of my recommendation list at this moment in (time. You have to make an appointment with the chef, not a reservation - an appointment, and when you go for dinner he just brings you pile after pile of food, you know not what till it arrives. Mysterious enough yet? You have to go - trust me, you'll love it!"
(In my opinion, it's definitely an experience worth having, but be prepared for a whole lot of cabbage, egg noodles, and paprika.)
