The pitch is Argentine beef, but whatever the source, it was a decent steak and properly prepared. The restaurant seemed to have a Italian twist to it and some menu items were more Italian than Argentine or German.
This is a pleasant and easy place for lunch or dinner and it's close by several hotels in the area. I went early, just as they opened up for dinner, and got seated and service in reasonable time.
The night before, I went to a popular chain steak house in a more tourist-prone area and paid twice as much money for lower quality steak. So this was a good find. I would go back again.
An entrecote, (230 gr), roasted potatoes and a large bottle of San Pellegrino totaled to 21.60 Euro including service and tax.
