The ground floor back room of Henry Pordes - further down the Charing Cross Road towards Trafalgar Square - has fewere titles but comparable stock to Lovejoys. Yeah, OK, I get stuff from Lovejoys too. Upstairs.
Oops should have said 'unless you are in possession...'
Tend to pop in the Lovejoys once a week as I work 10 minutes away. Once bumped into someone from work right outside who clearly didn't believe my First World War excuse!
May have to give Henry Pordes a look next time as well.
