For me, a middle aged woman who likes cultural things more than shopping.
DH and DS3 are going to Warhammer World, its like Mecca to them and they will happily spend two whole days in there. I decided to come with them and amuse myself going to museums etc but I have just discovered Nottingham castle is closed for restoration.
If there's a John Lewis I could probably spend a morning or afternoon in there browsing and choosing a new potato peeler very carefully but I need other suggestions including somewhere nice to go for lunch.
I am not a big shopper but do like a good craft shop or secondhand bookshop.
I would particularly welcome quirky or hidden gem type suggestions and would venture out of town as long as its on public transport (I'm from a very rural area and not confident about driving on unfamiliar busy road systems).
