Actually, in my opinion, SF has the best food in the US, but Chicago is definately a close second.
So you'll be close to lake Michigan and Navy Pier..definately go to Navy Pier...there are lots of shops, restaurants and stuff in that area, it will be super fun! The Nightlife is great in that area.....I think the Cubs play close by (my lil sis just moved to the area and 5 of the cubs live in her building).
Im jealous you're goin to the NCAA games there..If UK Wildcats end up playing in Sacramento, I know I'm going to be there
