The Hatters is a fine, unspoilt old pub - it's nice to go to a place that hasn't been modernised, and still has several cosy rooms around a central bar. And the floral display outside is terrific!
But it's very much a locals/regulars pub - a newcomer dropping by for a pint can sometimes feel a bit out of place.
One of the hallmarks of the very best pubs is that they are places where anyone can feel welcome, even if they are calling in for the first time. On this particular criterion, other pubs in the area, such as the Sportsman and the Ring O' Bells, are more sucessful.
