The first time, I was floored by the fresh preparations and unique take on Austo-centric grub. The second trip, I ate horrible overcooked pork on a bed of what tasted like canned red peppers. I'll try it again, though, because good food is hard to find in Vienna and the first trip was a winner.
Service was okay the first time if a bit grumpy. Second trip there, the lady was super nice and efficient, but she was the ONLY server working the entire outside area and was totally overwhelmed. This being Vienna, nobody running the restaurant thought it was a good idea to get another server out there to help out.
