It would stretch the definition of "diary" a bit, but I cannot recommend The Dept to Pleasure by John Lanchester enough. This book had me hanging on to every page and I just couldn't stop reading it once I began. The trouble is that trying to explain what the book is about without giving away the surprises is practically impossible. Let's just say it's about a man taking a journey around France while talking about food. But, this is not a book about food, even though there are recipes in the book haha. Like I said, I can't tell you WHY this book is so good without delving into spoilery territory. The best way to read this book is to going in completely unaware so try it and let me know what you think.
