I was very impressed by Northwestern and am ecstatic to have an acceptance there. With that being said, I've learned a lot as I've gone to other interviews, and I don't think Northwestern is as unique as it markets itself to be. This may sounds cynical, but in the end I think that all upper-tier medical schools will give you more or less the same education and opportunities, so things like "mall-like facilities!" and "an innovative PBL curriculum!" aren't huge selling points for me. Location, on the other hand, definitely is, and NW gets a big freaking gold star in that category.
