Permanent exhibits? There are always new exhibits at the Field Museum. Science Museum exhibits are kind of dated (imo) but they do have new shows in the planetarium from time to time. The Shedd has their coral reef exhibit (perm exhibit) which I think was new about 10 yrs ago.
Um ... do you mean Alinia? If so, no ... I'm not really 'into' the 'ultra-fine dining' experience. Although I would like to go to Acadia, as it's in my neighborhood. And it's only 2-star rated, not 3 ... so it's only 'super fine' vs 'ultra fine'
