Betty's of Harrogate (or York, for that matter). Been there since 1919, a Yorkshire tearoom with a Swiss twist. It's changed very little in the meantime! It's particularly fun to go to the York one on a Friday evening, just as everyone's starting on their night out (the Stag & Hen parties especially). Watch everybody pile out, half-undressed, on to the street, full of drink, as you sip from a cup of tea, eat some brown bread ice cream and listen to the piano.

(And then go and join them...)

The Cosy Supper Bar on Whitecross Street in London, near where I Used to work. A proper, old-style chippy with giant mugs of tea, formica tables with plastic seats bolted to them, and an all-pervasive layer of beef dripping that's been there since the 50s. Artery-clogging and great - but when will Southerners learn that cod is the wrong fish for this...

Also, the Quality Chop House in London EC1. Way overpriced, but it's an absolute gem of a place. Proper British comfort food, and the restaurant itself should be (if it's not already) registered as a site of historic interest.
