>>> Why would you go to Liverpool?
Er, possibly because it's one of most popular tourist destinations in the UK (ranking ahead of cities like Oxford, Cambridge and Bristol in visitor numbers), a Unesco World Heritage Site, home to some of the finest art galleries in the world, has stunning architecture and great nightlife together with the fact that it's by far the friendliest city in the UK (even ahead of Sheffield in that respect).
