A river runs through it

Bluewater shopping centre. Not usually my cup of tea but on our way home we can stop there for a Carluccio's ' magnificent' breakfast.

It's the first time I've noticed that the pattern on the floor has a meaning: thanks to my attractive assistant for pointing this out.

The grey wiggly line denotes the route of the Thames roughly from source to sea with the towns marked. Clever. I'll never get lost again.
