This type of 'cooking' is a joke on the wealthy
Just like the over inflated and extremely hyped art world, restaurants like this one are all flash and no substance.
Nothing they attempt is to prepare great tasting food or extra special hosting and comfort for their guests, it's all about creating press releases and using the most expensive ingredients and labor intensive recipes possible so as to charge massive markups on the food.
Everything is about entertainment, oddball effects, weird textures, and shocking the patrons. Nothing intrinsically wrong with food theater, but personally I'd rather have a big fantastic bowl of lamb stew than have my taste buds shocked but some odd foam/gel infusion. It's all a joke by worn out chefs who care more about becoming wealthy than putting in an honest day's work.
And the rest of the world seems to agree, as the subject restaurant of this movies apparently closed now.
