I loved it! Save for The Incredibles, it is my favorite Pixar to date. I really made me want to see Iron Giant again (BRAD!

). The film also made me want a glass of wine. Now, that's good animation!
Ego was probably my favorite character because his decor was very over the top. The coffin-shaped room, the funeral decor and the skull typewriter (which I read about afterwards) made him quite the bringer of restaurant death.
The artwork was wonderful. Of course, how can you go wrong with Paris as a subject? I also loved the ending credits done in a Ward Kimball-ish style. And, as always, I found the homages to other famous films to be charming and fun.
I can't wait for it to come out on DVD so I can study it. I get the feeling there is much more that I missed on first viewing.
