Recently we have been there with our friends from Aachen. The menus were brought immediately, and five minutes later appeared the waiter eager to write our order.
"- They are not very friendly here." came an automatic comment as the lady left
"- Right, but very efficient!"
Indeed, it is expected here that you surely know what you want, and want to get it quickly.
It is amazing to follow the speed of the waiters running around and serving a huge number of clients. How they achieve it? -No redundant movements, words, jokes etc. Efficiency comes first.
I never though that I would say this, but this type of "imperfect" service fits well in this place :) It is not the best restaurant to ask for dish recommendations or expect some gourmet food, but the traditional choice "Sausage and beer" will always be the right one.
Efficiency comes at the price of friendliness, which is considered time-consuming luxury. A strange business model, but the business is successful. Surprising? Yes!
Maybe because the clients know "the rules of the game". They know what they come for: tasty local food, authentic atmosphere, picturesque view. As soon as these requirement are met, clients are happy and ready to return. We like as well to play this game from time to time. And you?
