Charlie's interest in food ensured that he kept a record of the places where he ate when working in the City of London. The main places that he visited were;
B.T.T: Cafe or other form of eating-house regularly used by Charlie. Full name of the premises and its location are unknown, but it must have been within easy walking distance of his office at 85 Gracechurch Street.
Cambrian Dairy: As for B.T.T. Also referred to in the diaries as 'the Dairy'.
Princes: Less regularly frequented by Charlie, but visited particularly when he was meeting his brother Harry for lunch.
