I felt compelled to respond to your strange review. Keep in mind the title of the book is "MODERN Cafe". I would consider a menu item like Octopus Salad a pretty nice item at a cafe and, if prepared well, would likely do well in my city. If it won't go over well in your area, come up with menu items that will. The book is intended to give ideas to the owner, not have all the answers and come up with a menu for your business. Development of a menu for your cafe is your job.
As for your comment about readers not being able to follow directions because they aren't adept at baking/cooking, the author of the book clearly states in the introduction that he intentionally doesn't give basic education. It's simply not the intent of this book. Someone wanting to open a cafe who would be "confused", as you say, by the creaming method should hire someone who isn't or should think about starting a different type of business.
No one book can be all things to all people and I find it unfair that you would leave negative comments because you didn't read the introduction or because octopus salad won't sell in your town because you and your local residents would find it "snobby".
I personally found the book well written and inspiring. It gave me some great ideas for my business.
