Don't know Ashtead. Wimbledon/Putney - a few years since I went drinking around there.
Don't really drink in Sutton since moving away from there - used to drink in what you term the dodgy end, knew plenty of people so never had a problem. Currently, prefer the pubs around Carshalton & Wallington, better places if a tad expensive at times (Youngs, please note), and by and large
better people. Would rather pay the extra if it means the scumbags can't afford to drink there.
