Try This.

Daniel Freeman is a food writer, restaurant critic and also the founder and writer of the blog restaurant girl.com. 

Try This is her guide to eating fourteen of the world's cuisines. 

Each chapter deals with a different cuisine which she explores through restaurant meals mostly in NYC and Los Angeles. In each chapter she describes and explains the food of the country she is focusing on. Each chapter ends with information about how to order and put together a meal and explains the etiquette and acceptable table behavior in each country.

I feel this would be an informative book for a novice diner. For someone like myself who dines out a lot, cooks everyday and reads plenty of books and magazines (not to mention blog posts) about food there isn't so much in the way of new information. In fact there were a few things in that I consider to be incorrect - maybe this is because the book is really about the foods that you find in ethnic restaurants in the U.S. rather than the food in its own countries. 

Despite the above quibbles I did enjoy reading this, it was light and amusing and if you are interested in becoming a more adventurous diner it would be an informative guide. 

( Note - The book was published in 2011).
