I bought the book because I love the travel articles in Hadassah Magazine. They are consistently fascinating and well written. The book offers Jewish history, customs, and local color of 100 places, both familiar and exotic. Only two things could make it better: I miss the photos that are published in the magazine; and the articles should be dated. It's still worth reading, even if not current, but since phone numbers, restaurants and hotels change over time, readers should know when each article was written.
The articles are detailed and interesting. HOwever, the book does not cover asia or the south pacific so it is not good as a guide to world jewish travel. The Ben Frank book lists more restaurants but this book tells you the historic significance and current sites of interest to the jewish traveller.
