VEGAS! ! !  was there last year.   
You have got to go to the Ghostbar (Ultralounge) in the Palms, amazing.  Open air club/pub on the roof, there is also a glass dance floor on an overhang so you can see the ground below  
Voodoo Lounge at Rio also good, nice restraunt up there. 
Grand Canyon in helicopter is a must too   
Too much to see and do.   
I found out about a pub that has 500 beers when I returned   It is called the Freakin' Frog and is accross from the Nebraska Uni. 
  
SAN FRAN - Was there a few years back, still may favourite US city.  Watch out for the guy that jumps out of the bushes in Fishermans wharf, he is hilarious.......and totally insane 
  
Have a good one mate   ......wish it was me...... Portugal at the end of September though
