a good meal at Boettenrs on the 26th May was destroyed by the extraordinary behaviour of our waiter. on a bill of 724EU, we left a total of 800EU on credit card. we were dirtectly challenged by the waiter on leaving the restaurant who informed us that our meal had been 'perfect' (!) and that out tip was not up to his expectations. In 20 years of dining, I have never hasd such an unpleasant experience in a restaurant, and can only urge other readers to avoid this restaurnat, and go to elsewhere.
