Until two weeks ago I hadn't been to Fisher since Hamlet last played Athletic at Surrey Docks. I enjoyed my visit. Supporting local businesses seems pragmatic to me, rather than them trying to muscle in on any particular market.
They used to get 70 odd at Hamlet. They got 262, from memory, on Saturday which was the 7th best step five gate in England. People clearly like what they are offering. Good luck to them.
Their ground ensures they can never be a real rival to the Hamlet on the pitch again, unless Hamlet stuff up badly. I can't see how Fisher offering local beer and vegan food is any threat to, or any business of, Dulwich Hamlet.
