Came to Chicago for a mid-week solo vacation adventure. Picked this walking tour because no matter how many times I've come to Chicago I never seem to get to see the sites or check out the tourist spots. Our tour guide, Allen, was knowledgeable, excellent communication skills, and kept our group of 20 people together extremely well. I now feel like I know the city better, and some of the history as well. I would recommend this to anyone visiting Chicago, whether it's your first time or your 10th. I had a great time!!
