Very unfriendly staff. We just wanted a couple of vegetarian burgers and some soft drinks. We had to repeat our order several times before the waiter actually listened and comprehended it, even though we spoke German.
This branch is located in the "am Brühl" which is a big modern shopping center. The staff were nice and kind the food as usual. But I could take my dog inside! That was interesting and pleasant! So we enjoy our time there!
