Odd one, but cash points in the UK are amazing. You can pay in, check balance, transfer, give to charity, top up your mobile phone.
Not needing a good samaritan law.
Humour.
The choral music coming out of the UK in the last century is some og the most beautiful. Or maybe it just 'speaks' to me more than Bach et al.
Period dramas. We do them very well.
No VAT on children's clothes and shoes. Free contraception. The NHS.
Gothic architecture.
Multi culturalism. It is so good to get off the plane and see people with different colour skin!
Signposted pathways through the countryside.
Culture generally - there's a lot going on in the UK. Always a show or a concert or comedy you an go to.
The BBC. I know it gets accused of bias etc but generally it's pretty bloody good, and invests in new talent.
