I remember visiting Mozney holiday camp in Meath, Ireland (sort of like Butlins in England, only worse) many many years ago and the arcade there was stuffed full with beautiful Atari machines.
They also has some kind of Atari 'Computer Zone' where you could join a room full of easily excitable children playing Atari 7800 games.
ArcadeFlyers.com lists 5 games under Atari-Ireland, none of which were Atari games anywhere else in the world. Incidetally, Dragon's Lair and Space Ace were both animated in Ireland (by Sullivan Bluth Studios).
