Inside what was the Centurion Tower at Caesars Palace is now the hushed first hotel by star chef Nobu Matsuhisa. The quiet and distinctly Japanese sanctuary’s rooms combine grass cloth, mixed woods, an unconventional nod to the flowing ink brushwork of Hitsuzendo on the walls. But the David Rockwell-designed rooms, with their teak and natural Umi tiles, belie the high-technology underneath it all. Special elevator technology delivers you straight to your floor (no taking the local); and a special app lets you order Nobu in-room-dining 24/7, reach the concierge, and even order housekeeping from your smartphone. The largest Nobu suites have their own sushi counter space for personalized chef service.
