The food was good and came rather quickly. The service is what makes it go all the way to one start. From the moment we entered, we were not greeted, only asked if we had a reservation (which I could not book via phone, as they said "just come over and we'll see"). Then we're asked to wait, whether to be seated or to check if tables were still available was not clear. We get seated a few minutes early, and we're told that we could only pay cash (in 2024). I had cash, so said ok, but immediately decided I would not tip because of this. We get the order, they bring the drinks and roughly drop them on the table without a glance at us. Food is good, we eat up, ask to pay, the bill is just over 40€, I hand the waiter a 50€ banknote, and after several seconds of silent in action, thr waiter asked "how much do you want to pay?" Basically asking for a tip. I said what's on the bill, I would have tipped if I could have paid by card. The waiter took very poorly to this and made no efforts to hide his malcontent. Only after we left I realised we didn't get a receipt so who knows, maybe they did get their tip, only from the German government rather than from me. First and last time, I'd much rather give my money to someone more wholesome than these individuals
