We have eaten there very often with various family members and friends, but last Sunday it was not good.
Had to wait a very long time for the main course (the plank) and then also paid for an extra bowl of fried potatoes. Despite the fact that we ate well, this did not give a pleasant "aftertaste". While the waitress specifically asked us: "Everything you want, can I add something for you?"
As far as we are concerned, this is not a reason to charge extra, of course it is not about a few euros, but the idea. Unfortunately!
