What's your favourite greasy spoon cafe?

Regency Cafe, Pimlico - as seen in Layer Cake (bloke gets thrown about a bit in there). They sell orange juice in milk bottles and there's a woman who bellows your order from the counter when it's ready. All in all a terrifying and delicious experience.

I'll say hello if I see you in there.
