The Royal Oak I was trying to look on the bright side of wintry London, even though the weather was densely dull and cloudy. It eased my guilty conscience by pub crawling from the morning. I looked in at the "Stonewater" book store in Piccadilly Circus in the morning, and bought a copy of 'London Pub Walks' which was published by CAMRA, the Campaign for Real Ale. I read it in the in-store lounge. I picked out "The Royal Oak" pub near London Bridge and went there. There were a bunch of regular, elderly customers perched on the bar stools. The ale and sardines I had there were very fresh, substantial and the price was very reasonable.
