I was at Newport a year ago (almost to the day). It is very cool. However, it has 10X more fresh than salt. That being said, I am glad that I went. As for the Shedd,you cannot go wrong. It is one of the oldest (if not the) in the country. Tons of exibits, a full day plus. BTW how are your going to get to CHI-town in 4 hours???
LOL
If you are spending thenite check out Millers Pub. it is at Wabash and Adams. Under the L. Great ribs, just a fun place to be.
