The Hamburger: A History Book

I thought this was a relatively light/food history book. It focused on the differences between a sandwich with ground meat and an actual 'Hamburger.' I was disappointed in its overall history of the hamburger. I was expecting more "meat" in the conversation. Ozersky spends a lot of time discussing McDonald's (makes sense) but not enough on other burger chains. In addition, this book was recently published and yet devotes about 5 pages to the newer hamburger story. There was no mention of the hamburger cooking contests or newer re-invention or flavoring of hamburgers.
