The Nobu Brand how it is evolved globally in the restaurant and hotel industry

discuss how the Nobu brand expanded from one restaurant in the US to an international brand including hotels globally. I wanted to analyze and discuss the benefits as well as difficulties Nobu encounters in trying to keep with the standards, service of all of his brands while also having to deal with rules/regulations of the countries he decides to open up his properties. (Dubai, Russia, China, Europe) What does each country bring as obstacles and benefits?
