Vitesse, I think you're kind of missing the point here--these are ALL original menus. It is their choice to determine from where they'll
take inspiration, what they'll do with it, how they'll interpret it, what the utensils will look like and what the desired effect on the diner will be. Next "covering" another's menu, whether it be another chef or standards from another cuisine, is still original to me. That's not to say that it's necessarily what I want to eat--for example, their take on Thai just didn't appeal to me--not because I can get the "same" item in another restaurant but because their creations didn't sound that tempting to me. And, while Next is cheaper than Alinea, it's still a high dollar ticket (no pun intended) so I'm going to allocate those dollars carefully.
I think you may need to accept that they are not like other restaurants--because of who they are, they get to essentially do whatever the F they want--and the vast majority of people love it, even if certain things don't work or don't thrill or whatever the expectation. They have a model and a reputation that enables them to do something that most businesses only dream of--exactly what THEY want with people clamoring to buy. And from what I've read and heard, even when they disappoint or miss, it's still judged as an overwhelmingly positive experience (and it IS an experience, as opposed to just a "meal").
You, with, perhaps, more traditional expectations and desires, may just not be their target audience. Not that there's anything wrong with what you want. You just won't find it here and they don't have to give it to you.
And, for the record, I'm not sure I'm a fan either--I'm going to Childhood after a somewhat less than wonderful experience at Paris. But I can value what they're doing, admire their amazing success and applaud them for it, maybe only from afar in the future
Regardless, I believe that having Next in Chicago enriches our food scene, positively inspires other chefs and represents the ultimate entrepreneurial venture which I can appreciate.
