Despite my proximity to Richmond, haven't been to the Green Howards Museum since it reopened recently after a major refurbishment/upgrade which by all accounts has been done to the highest standards and per Trip Advisor is even 'dog friendly'!!!

Also when in Richmond another suitable spot is Richmond Station and its Restaurant
