McGoos, formerly the Palace Picture House, was THE mod hangout in mid sixties Edinburgh, located at 18-20 High Street, opposite John Knox's house.  The frontage of the building complete with engraved Palace Picture House logo is still present, though the structure behind has now been demolished.  The Who also played here, but I don't yet have a confirmed date.

Boarded up but intact, in the mid seventies.  Thank you to www.henniker.org.uk for the photo
