Hyatt Regency Chicago - Chicago
Chicago looked gorgeous from our balcony. Hyatt Regency has a fairly good bar, where there is a lot of space to move around and is not squishy. We just took our breakfast from here which was a buffet but had great amount of variety. The rooms have plush beds and numerous munching options. Bathrooms here are the best! If you want to spend some extra dollars spend them here.
The room was warm and cozy over looking the Chicago River.Waking up in the morning,I looked out of window and the weather looked perfect for going out and getting rid of jetlag. Instantly reminded me of Honey Singh's song-Blue and pani ,Din hai Sunny.(I had not discovered the windy side of Chicago until then).
Navy Pier - Chicago
Navy Pier is sheer excitement! You have boat tours, rides, shopping, food everything. It's a heaven for kids and some of us looking to unleash the child within. The boat tour throughout the city is a good deal mainly if you are short of time. In fall the Halloween decorations are a treat!

Lakefront Trail - Chicago
The Chicago Lakefront Path is a beautiful promenade next to the harbor. Starting from the Hyatt Regency,in the company of a collegue,I walked all the way along Chicago Lakefront and Navy Pier which is at the shoreline of Lake Michigan. Folks of all kinds were enjoying the lake by running, cycling, roller blading, boating, walking or just sunning themselves.
The Bean - Chicago
Most touristy place in Chicago, The bean has a weird aesthetic appeal to it. Millennium park houses various events throughout the year, if you're lucky you can get into one. This place is modernly artsy. You'll love how shiny, spikey and full of shapes it is here.
Cloud Gate - Chicago
Called as "Cloud Gate" Its glass-like reflective surface provides distorted images of Chicago skyline and visitors feel amused to see their warped reflections on "The Bean".The concave underside allows visitors to walk underneath to see the omphalos, and through its arch to the other side so that they view the entire structure. It was fun sitting in this place and seeing people of all sorts-from teenagers trying to capture the perfect reflection to couples trying to take a perfect selfie,Guitarist playing,singers singing.We encoutered a preacher who preached us about "Universe,GOD,Life,Human existence etc etc etc for like 30 minutes.

Jay Pritzker Pavilion in Millennium Park - Chicago
The Signature Lounge - Chicago
Located on the 96th floor of John Hancock Center in the Magnificent Mile "The Signature lounge" is one of the most iconic buildings in all of Chicago with a truly incredible sight.There is a restaurant on 95th Floor and Lounge on 96th Floor. I visited this place 3 times while in Chicago. It is a gorgeous place to sit down and watch over the city and see forever.The elevator is incredibly fast for going up 96 floors and we found ourselves popping our ears. I am not a much of Foodie and drinker,so wouldn't comment much on that but food and drinks were mediocre Only the views are the definitive selling point of the Signature Lounge and not to forget-The views from the Ladies Restroom are incredibly stunning.
Wrigley Field - Chicago
Our US stakeholders took us to have a Cubs experience.I am not much of a sports person,so was unable to pick up the baseball game.But the field experience was awesome - Beautiful stadium, tons of green, no flashing lights,crunch of peanut shells under the seat,watching super enthusiastic crowd singing in Chorus and a chance to soak up the sun while trying to understand the game.
