There are signs saying “Fankfurt Christmas Market” so yes indeed German, although I’m not sure what the qualifying criteria for the Frankfurt bit is specifically.
Credit where due though, it is very large and very pretty and would be quite a romantic place to have a beer or mulled wine at a quieter time. As mentioned previously the crowds needed managing on Saturday and it became (imo) quite dangerous, particularly at the top where the steps/fountain are.
Bratty’s were £6-7 and beer about the same, which is probably about the going rate for that sort of thing.
I quite liked the stuff for sale, typically German Christmas Market fayre, but that’s what keeps it festive and unique. Would rather that than go all out chavvy fun-fair or have stalls selling T-shirts and whatnot.
The crowds were a nightmare and their litter was shocking, but thought the rest was pretty damn good.
