I signed up for this tour ahead of time in anticipation of visiting St. Louis to attend my wife's cousin's wedding. It cost only $10 plus processing fee. I invited my wife, my daughter and son-in-law to join the tour. We met up with the guide in front of the old court house and there were about 20 of us in the group. The tour lasted about 2 hours and 15 min altogether. Our guide Ryan, born and raised in St. Louis, is a history teacher in town and also works at the MO history museum, Ryan was one of the best city tour guides that I ever had anywhere in the world ! He was simply superb, talking about all kinds of interesting stories related to each building and attraction we passed by. He was very attentive to each of us, answering every question patiently and effectively. He basically knew everything about St. Louis. I had no idea that this city is related to so many famous people and incidents in the history of US. All of us learned so much about this city. He was also very funny and entertaining as well. The time went by so quickly and we were all very impressed with the whole tour. We actually ended up missing going up the famous arch and we were still absolutely glad we attended this tour instead. I would highly recommend this tour to anyone.
