One of those "hidden gem" places, as it's basically in the middle of nowhere in Moon, about 12 minutes from the airport. Reasonable prices gets you tasty Eastern European cuisine; I had the gulasz with pierogies; loved the way the pierogies were cooked, and the gulasz was quite tasty as well. You can't find Eastern European food too many places in the Pittsburgh area.
This is primarily a takeout place; a single table sits outside for eating. So mostly you're going to be taking their food elsewhere. But I'd wholeheartedly endorse giving them a try.
