Pizza Express Cowcross Street, London

There are three distinguishing features of this Pizza Express, located in Cowcross Street (so named probably because cows used to cross over a tributary here on their way to the slaughterhouses and markets of Smithfields, just to the south).

First, it has two stairways to the downstairs, rather than the regular one. As if that is not exciting enough, it also has unusual, and rather stylish, handles on the men’s toilets. (My investigatory zeal did not take me as far as the women’s. I apologise.) And finally, there a rather natty fish mobile on display in the window.

It also holds the record for the longest gap between entering premises and sighting a member of staff. Two minutes and thirty-one seconds. Approximately. But it was a slow bank holiday afternoon.

So that is 19 down, 119 (or thereabouts) to go.
