It's a hotel within a hotel. On Monday, the first-ever Nobu Hotel -- yes, from the same team behind the uber-popular Nobu restaurants -- opened in the Centurion Tower at Caesars Palace Hotel & Casino. This luxe 181-room hotel, situated next to the also newly-opened Nobu restaurant, is all about the details. It may not have many on-site amenities (although guests are granted free access to Caesars's facilities such as the fitness center and PURE Nightclub), but it does offer special perks such as 24-hour room service from Nobu (only open to non-guests for lunch and dinner) and in-room hot tea upon arrival. The luxe rooms, designed by renowned hotel designer David Rockwell, are in keeping with the Japanese theme: Floorplans exhibit feng shui, and minibars are stocked with Japanese beer and sake. But take a look for yourself after the jump!
