You and the wife, or with kids?
Railway museum was very good for either of above and the cafe there had very high quality sausage rolls and bottled beers.
York chocolate story was fun particularly with kids, and masses of handmade truffles at the end.
Yorvik was a bit ‘mleh’ to be honest, kids enjoyed it and if you like archaeology it was interesting, but they got a bit bored of that bit and rated it more on the smelly ride near the end.
York castle museum was good. Had a very thought provoking ww1 exhibit, which I’d have spent more time on, but again kids were a bit bored. Good to go in Dick Turpin’s execution cell though. Not sure if the ww1 bit will still be there.
Great city, we had a week there last summer and would deffo go back.
