For those who dont know it, the thing with "tea" and bisquits... an English bisquit is actually a cookie, the most popular being "Digestives", once falsely claimed to have a soothing effect on the, er.. digestive process. Of those, Chocolate Digestives are thought to be divinely inspired, or at least, bigger than Rod.
The other item a lot of folks would miss is the Cheese and Onions in Yellow Submarine Sandwich. The cheese and onion sandwich is hugely popular in the UK, and the virtual staple of the pub goers for midday meal. They serve it between thick bread, smothered in butter, with a slab of cheddar cheese (white) and about a half inch of onion on top of that. That, coupled with the warm beer and ale...and occasional Scotch egg, contributes to the London fog effect.
