The Empty Bottle sounds like an excellent spot to catch some live music. They offer affordable drinks, reasonable cover, and a fun crowd. It's interesting to note that the bar started as a cat-filled hole-in-the-wall in 1992 but later moved two blocks up the street to a slightly larger and better-equipped venue. They've been putting on great shows for the past 20 years and have managed to maintain their success thanks to their low prices, lack of attitude, and loyal customer base.

The Willis Tower, previously known as the Sears Tower, is in downtown Chicago. Completed in 1974, it is a 108-story building that held the title of the tallest building in the world for nearly 25 years. It remains the tallest building in the United States. The Skydeck, located on the 103rd floor, is the building's observation deck, approximately 1,353 feet above the ground. It is one of Chicago's most popular tourist attractions, welcoming about 1.3 million visitors annually. Recently, renovations have introduced new glass balconies with floors extending four feet over the street. The balcony provides stunning views of Illinois, Lake Michigan, and neighboring states Indiana, Michigan, and Wisconsin on a clear day.
