Crossways is my local caff, on Evelina Road. It's a traditional greasy spoon, plastic fixed chairs, regular customers, exceedingly friendly staff. They'll bring you buttered, untoasted white bread as well, but the rest of the ingredients are of a good standard for this level of caff. Mushrooms are succulent and not deep-fried to death as elsewhere; hash browns, beans and fried egg are all par for the course; and there is a good sausage provided as well (a vegetarian one, since that's what I was ordering). Comes with (instant) coffee, or tea.
Address: 93 Evelina Road (on the corner of Kimberley Avenue), SE15 3HL.
