Deserted Cafe

I often used to call in at this cafe near London's St James's Park tube station to pick something up for breakfast.

A few days ago it wasn't open.  It hasn't been open since.  It looks just like the Marie Celeste.  Nothing to suggest it's shut for a holiday nor any of the usual signs of going into administration.  All left neat and tidy, just empty and cold.

It's a mystery.
