My favorite strip hotel hang out place.
Favorite bars: Vesper: get the Manhattan or Sazerac. Chandelier: Butterfly and Cosmo. Make friends with the bartenders and they'll even make you their own special signature drinks.
2nd floor west end area (where the have the conference ballrooms) great art display, from sculptures, to wall decors, and even the furniture. Where can I buy those, seriously?!
Had friends visit Vegas couple times and stayed at the rooms. A defo must! Either a city view or fountain view - still a great view! Even the room decor and furniture are eye candy. Seriously, where can I buy those art works?!
Restaurants? Holsteins: great but I'm not really a big fan of burgers. But great drinks. The secret pizza place? Well, you'll have to look for it and once you've found it, it's worth the search.
