My fiancee really loved WUSTL. It is a beautiful school, and the admin people are amazing. Granted, neither has anything directly to do with the law, but I think it does have a great deal to do with how much you will enjoy law school.
I chose Notre Dame over WUSTL after a lot of thought. I had a full ride to WUSTL and ND would cost me around 23k a year. That being said: (1) I'm a Catholic boy (2) I think ND might be the most beautiful campus I have ever seen (3) I hope to work in finance, and your common rich folk know ND, lawyers do know WUSTL though (4) I prefer Chicago over St. Louis, though St. Louis is an awesome city to party and hang (5) NOTRE DAME FOOTBALL!
Either way, you can't go wrong with WUSTL. It is an amazing school. If I never got into Notre Dame, I would be stoked to go to WUSTL. I would catch the trolley every day up to Busch Stadium and catch a ball game. It's a great school in a great city.
