If UnRisk was a Restaurant
It was most probably the Maze in London. It is one of Gordon Ramsay's restaurants. As Gordon Ramsay, the Chef of Maze, Jason Atherton offers dishes as result of a, what I would call, mathematical cuisine. He demonstrates that simple cooking methods and reasoning (instead of unconstrained combinatorics) are often the best when creating best dishes. At Maze they offer a tasting menu with small dishes for a scalable meal of your own choice. The service is perfect. They are interested in what I want to eat and drink and not what they want me to eat and drink. They never give false comfort about their offerings.
