QotD: My Favorite Greasy Spoon

What is your favorite greasy spoon?
Submitted by S@ngarang.

The St. Giles Cafe in Oxford is very good, and they give enoromous portions, but it's always packed out with hungover poshos.  So my vote goes to the Cafe On The Hill on Brixton Hill.  It's a combination between a traditional greasy spoon (so, as you'd expect, you can get stuff like liver in onions and quiche with your bacon butty) and a Thai cafe, with a menu that changes all the time.  The food costs virtually nothing, the opening hours are entirely random, and it's the only place in the world where you can enjoy your enormous plate of fried stuff sitting next to a clown in full make-up eating tom yum soup, a Guardian-reading eco-couple with hemp-clad baby enjoying a few pieces of black pudding, and prostitutes from the corner of Josephine Avenue discussing last night's johns over a plate of chips and some tea.
