Design seems to be an extremely important aspect of restaurant success. Nick Haque's Koi restaurant acheives this because he is the visionary of the entire project. Handing over the entire project to a team of designers would be a disaster. There would be no coherent goal of what the restaurant should be.
In this care, Nick is the one who envisioned what the dining experience should be like. As the investor, he cares a lot obout whether or not the restaurant will be a success. This helps when someone is trying to make sure the vision of a fine dining experience is being fulfilled.
Nick Haque's Koi restaurant has been able to take this vision and apply it to different regions. The restaurant is expanding constantly, but each restaurant has the same goal: comfortable and memorable dining experience.
