Nothing in here is actually "a menu" but still...
In the train station, Waterloo:
Around the corner from there:
The "chilli" might be followed up on. When we were at the Jane Austen tearoom in Bath, I asked what kind of chilli (about a sweet corn and chilli soup) and the waitress went to ask. She came back and said "regular chilli." Then at a roadside McDonald's I saw something that said chili, and it looked green, and it was chopped up jalapeño, so... I don't know.
Not a menu,but interesting:
And in Burger King at Waterloo Station (where I got a fish sandwich, because I know that one, and I was hungry):
