The interior of a huge, lean-to greenhouse, Victorian or maybe even older, where the vines are rooted outside come through the wall and are hanging on wires up in the roof. They are also festooned with bunches of succulent looking black grapes.
That was all very interesting but perversely the Two Terriers decided that the shadows on the wall were more interesting. Even if nobody else does.
You'll just have to take our word for the fact that there were hundreds of bunches of grapes up there and they were almost the colour of the shadows.
Sadly they were well and truly out of reach so we couldn't do a tasting.
