Reflections in a window give the illusion of another world within the frame ... and actually, a new dimension is coming to this empty space on Mission Street. I'll give you a hint with this verse from Through the Looking Glass:
A loaf of bread, the Walrus said,
Is what we chiefly need:
Pepper and vinegar besides
Are very good indeed --
Now if you're ready, Oysters, dear,
We can begin to feed!
That's right, South Pas will soon have a new bakery. (O frabjous day! Callooh! Callay!)
