Queen Elizabeth on 'Game of Thrones' Set -- You Call THAT a Throne?

It consists of a thousand blades ... was forged together with the hot breath of an ancient dragon ... but Queen Elizabeth II didn't seem to impressed today when she laid her eyes upon the Iron Throne.

QE was out in Northern Ireland checking out the set of "Game of Thrones" when she got up close and personal with the chair reserved for the ruler of the Seven Kingdoms.

During her tour of the set, Lizzy met a bunch of the cast members ... including Lena Headey, Maisie Williams, Sophie Turner, Kit Harington, Rose Leslie and Conleth Hill.

As for the Queen's REAL throne -- it's pretty pimptastic.
