This is one of my favorite movies ever but I'm not sure that the joy of tea was fully appreciated by Mr. Withnail and Mr. I in this scene at the Penrith. Yet everyone else stayed unflappably British and not a tea cup was broken nor any jars of lemon curd disturbed. But, according to this great website detailing the major filming locations of Withnail & I, this quaintest of tearooms doesn't even exist and is instead a chemist's shop.
