I was there just two weeks ago, and this was my first Vegas trip!
Make reservations at Nobu - Robert DiNero is has owner of this chain - They have fantastic Japaneses fused with western taste! All I can say is Delicio!!! I went with 8 other girls and our bill came to $780 ish.. thats including Drinks as well.
Make reservations at Tao - make late reservations so then after dinner you can go upstairs and party your buttocks off!! Tao club is the happening place to be in Vegas on a Friday and Saturday night.
Heads up: if you don't show up for your reservations, you get charged $50.00 per person at Tao, don't know about Nobu.
My girls went to Pure night club to party sunday [while I slept because I got the 24 hour bug], they said music at Tao was way better.
I went to run a marathon so I didn't get to do a lot of walking.
Shopping is just as expensive there as it is here in Mac town.
We watched Zumanity and it was great apparently.. It had a great opening, but I was woken up half way by the security guards. My friends thought it was great.
For breakfast we headed to Cesars place.. not worth the buck.. go to Serendipity --> and have their mixed berry smoothy, it's to die for!
Hope all that helps.
