Yes, in Leeds. About 15 years ago though. It had lots of lovely craft type stalls and I bought a really beautiful hand carved, hand painted wooden cat for a mere tenner. Lots of fantastic food stalls, funfair rides, all beautifully lit up, stalls and huts all well laid out and then a huge tent serving christmassy drinks with the best German oompa band playing in the centre. Everyone wrapped up in warm winter clothing and silly christmas jumpers. The atmosphere was so fun, friendly jolly crowds all involving each other, lots of laughing and singing - I went home very merry!
Then I moved down south and have been frequently disappointed by the very lacklustre xmas markets down here. And charging ludicrous amounts of money for the shittest tat & god awful food (by simply adding in 'artisinal', or 'curated' or 'handpicked' or some other wanky terminology) and rude people barging each other about... it's killed it for me. I can't be bothered with these markets anymore. There's no joy in them whatsoever now.
