The restaurant and the staff were nice. The food was good, even though - in my opinion - it had too much salt, but that's a matter of taste. The hamburger was good.I think that when you order an almost 10€ burger, asking for 3-4€ in french fries is a bit disappointing. I understand it's Vienna, and the city is expensive, but that would be the equivalent of charging for Wi-Fi. The kitchen closed before I could order something else.
