Well, in my mind the British kitchen is nonexistent.
I lived in the UK for a couple of years. Good food in the UK tends to be difficult to find sometimes. There is the full English breakfast. Some places barely bother having anything else on the menu, they just serve full English breakfasts morning, noon and night.
There is also fish and chips. I used to buy the most awesome fish and chips from a place in Essex, along the Thames estuary. It was one of my favourite places to eat on all my travels, the place was
always humming with customers, and they'd have 6 or 8 people cooking and serving in a small shop. And you can just go in and order a serve of chips and a cup of curry gravy, which comes with a tiny wooden fork to pick up the chips and dip them in the gravy with. That is soooo good.
I remember going to Cornwall, having eaten excellent Cornish pasties growing up and expecting more of the same in Cornwall. And then you get there and the people running the little cafes and restaurants are mostly semi-retired and from places like Yorkshire. So finding a Cornish pastie that hadn't come from a factory and wasn't better suited to being used as a doorstop than as a meal, was difficult. That said, the clotted cream ice cream in Cornwall is awesome and buying a "hedgehog" ice cream in a cone is great.
Speaking of clotted cream, fresh scones with clotted cream and strawberry jam and tea is great. I went to Harrods (in London) with a friend and that's all we could afford to eat at the cafe there. The food hall at Harrods is amazing, although the prices are outrageous.
Indian food is enormously popular in the UK for good reason. I remember going to a dead bodies exhibition and we passed by a street where I counted at least 38 Indian restaurants. We went back to grab a meal afterwards and almost all of the restaurants were packed.
