You can't go to Dublin without visiting the Temple Bar District.  Great Pubs, Great Music, Great Atmosphere.  Very few tourist traps in the world can equal this one for gettin your drink on.

If you don't feel like travelling all the way to Tokyo that night then Gaspanic Yokohoma is the place for you.  Be sure to go there on ladies night (Thursday Night) for 300 Yen drinks.  Well they were 300 Yen when I was last there in 2003 it has probably changed by now.  Gaspanic, TGI Fridays, and The Mall where the major reasons I went to Yokohoma, that is when I didn't feel like going up to Tokyo.

As far as landmarks go in Roma,  this is my absolute favorite.  Beautiful and amazing!  It is great to see at night and there is a pub right near there called the Albert which has the best Happy Hour in all of Rome and pretty close to the best Happy Hour I have seen the world over.  When it comes to Roma I know more about this city than any other so if you are going get ahold of me first.  I can tell you where to and where no to go.  :)

I think I spelled it wrong,  but next to Serapo one of the best beaches in Italy.
