We went here several times for breakfast. There was as a good choice for all appetites at reasonable prices. We also had a snack their one day with a selection of German dishes and prices which was fine (I am vegetarian and there was nothing specifically for me, but I managed to sort something out). All the staff we saw were friendly and spoke good English, and let me try out my German on them! They are open 24 hours, so one evening we just went in for a couple of drinks. Regulars were there playing chess on a couple of occasions so this feels much more like a locals' cafe too, not just for tourists. We felt welcome on every occasion, and would go again on our next visit.
