What are some of the favs of the UK...so I might know what to make when friends come over...and Ideas for nice dishes?

curry is always popular amongst the masses

Lots of Indian. Chinese and Thai. Some Italian. For fast food, a decent kebab shop.

You know what's getting kind of hard to find? Traditional British food. Seems like all the fish and chips I had in London were in Chinese takeaways.

English, Scottish, Welsh and Irish foods are quite popular here.

Lots of traditional pubs up here & particularly up in the Yorkshire Dales where you can find great traditional British food - roasts, bangers & mash, meat pies, toad in hole, etc.   I'm hungry now!
