I love Balkan House. Not only can you eat for around $15, but you get the most delicious food you can think of. It has a specific Balkan cuisine which reminds me of home. Some comments I've seen below say that it has "greek" salad but "greek" salad is served everywhere in the Balkans and it's not called that.
Their schnitzels are huge and very tasty and the dumplings are also really good. The greek salad is always fresh and their wine is also very good.
The staff is very friendly and will provide excellent service. They also do catering which is very cheap compared to other catering places, and for the money you pay you get excellent products.
Also tip for those who like desert, their Baklava is amazing and I don't think i've ever tasted better baklava than at Balkan house.
