A little bit
The first evidence of the restaurant's existence dates back to the 12th century. It came to fame in the 14th century, when King Charles IV brought vines from France to Prague and the Premonstratensians, with their skill, grew wine of such quality that, despite the unfavourable local weather, it was equal in taste to French wines. They were awarded a coat of arms by Charles IV, a cast of which hangs in the restaurant above the bar. Charles IV himself was fond of visiting these cellars, as it is well known that he was fond of good wine.
