We ended our Edinburgh trip, suitably, at The Last Drop, which is in the heart of the Grassmarket. According to our host, The Last Drop is where prisoners would go to get their last drink of whiskey prior to being executed.
From grassmarket.net: "...the Grassmarket used to be where local farmers brought their hay and other produce for sale. But it was also the location of one of the main gallows in the city and crowds would flock in huge numbers to see the public executions. The last Drop Tavern is located immediately next to the scene of public hangings which took place there back in the 18th century."
