So everything was going great. Second time we've been here and the food was amazing, love their burritos. Their cocktails and drinks are really the speciality of the place, great choices. However, the waitress just couldn't get anything right. She brought the wrong drinks, the wrong version of food etc. WE let it slide, you know, not wanting to make a fuss in a foreign country. It's an expensive restaurant, then at the end we try to pay with a card and of course they do not accept them, which is so strange because it's like a bar/club downstairs with like 8000 czk Champagne on the menu. It was pouring with rain and we weren't going to a cash machine and then back into the restaurant. We had just enough money for the bill without a tip. We gave her the cash and she asked about the tip. We told her we had no more money and that she has to warn foreigners that this place only takes cash, especially when the weather was so horrific. We should have also told her that she got our orders wrong and the bill would have actually been cheaper if she hadn't, but we're cowards!
