Query: waste of money waste of time

Wow, I bought the book thinking it would be a helpful how-to-guide, it was more like a BAD novel of someone who had spent too much time in the deep under belly of New York. Don't waste your money or time on this one it's not one bit helpful. Amazon[.com] sells better books for a successful restaurant, I know I found one and this one was not it!
