It was a nightmare to eat here
Beware, this is a tourist trap restaurant!
My family ate here during our stay, and when the bill came, the waiter there named Ondrej (I remember it clearly) overwrote our receipt by 100 krons and gave us a very lengthy explanation about the extra kron being part of the law, and even went as far as to say something along the lines of, "That's the amount you're going to pay. If you want to call the police, go ahead. It's part of the service tax." So my father paid the amount the waiter wrote over and told him to give us the new receipt with the amount he had written over on it.
That Ondrej didn't do so, and when my father called his attention, he gave it to us, but the amount was 100 krons short of what he wrote over.
In short, the extra100 krons went to his pocket, and had the gall to DEMAND the tip from us.
That was the worst experience I've ever had during my travels.
