Things to do in Chicago

Even if it looks like a touristic thing it's worth it!! The views from the river are great!
It's the best place to see Chicago architecture :)
There are lots of them. Take the one from the Chicago Architecture Fopundation and at least you for sure that they are going to give you the best info.
It's 28$ per person and the duration is 90 minutes

It is currently the fourth-tallest building in Chicago and the sixth-tallest in the United States. I recommend to have a beer or something else in "The Signature Room" on the 95th Floor. The views are reallly amazing, even more at night.

The Art Institute of Chicago is a major prestigious destination you must add on your list of places to visit in Chicago. The lion guarded building houses 300,000 works of art and is also a school. The general hours are: Monday–Wednesday 10:30–5:00, Thursday 10:30–8:00 Friday 10:30–5:00, Saturday–Sunday 10:00–5:00. Check out the site for info on current exhibitions and events.

GO SEE Millennium Park! It's in the heart of downtown Chicago and one of the MAJOR tourist attractions. There you'll see the famous Cloud Gate sculpture, which looks like a huge chrome bean. You also experience the cool interactive Crown Fountain, which is my personal favorite. If you arrive at the park first stop at the welcome center located at 201 E. Randolph Street in the Northwest Exelon Pavilion. There you'll find friendly guides that will help you plan your visit.

Go see Lincoln Park Zoo, it's a great place to visit and spend the day. The Zoo is free but parking is a little pricy and street parking is impossible. General hours are from 9am-6pm. Lincoln Park Zoo is pretty large and extremely educational. I think it's one of Chicago's greatest places to spend a Sunday afternoon . They also have paddle boats which is always fun. The neighborhood is like one big park full of families, joggers, and Sunday bike riders. It's minutes from the Lake Michigan.

If you're in downtown Chicago it will be hard to miss Navy Pier. Just look for the giant ferris wheel. Navy Pier is one Chicago's more popular tourist attractions. The pier is has shops, restaurants, live music, Lake Michigan boat rides, fireworks and Chicago's Great Ferris Wheel. Check it out! It takes about half an hour to go all the way around. If you're afraid of heights I don't suggest getting on, it's pretty big. Try to catch a firework show while on Chicago's Great Ferris Wheel.

Marina city is a complex of two cylindrical towers near the Chicago River Is a complex of two 60-story towers built in 1964 by Bertrand GoldBerg, a student of Mies van der Rohe.
Marina Towers have appeared on the cover of Wilco's Yankee Hotel Foxtrot.
are famous because the appear on the cover of the Wilco CD.

Ventrella's is a really great internet cafe in Chicago's Ravenswood neighborhood. It has a 1930-40's feel. The owner James is probably the nicest guy you'll meet in the whole neighborhood. The sandwiches are great and the gelato even better. I have become a regular in this place and definitely recommend it to anyone visiting Chicago. Images coming soon!
