Yes, my local one is nicknamed the 'Park Bench Arms' because it does tend to attract the all-day heavy drinking crowd. I sometimes go there during the day for a coffee (their tea and coffee is cheap compared to Starbucks/Costa etc.) when the 'family' area is mostly occupied by pensioners who are there for a reasonably-priced roast dinner or fish and chips. In the evening, particularly on a Friday or Saturday, it's definitely best avoided.
