Query: Not so helpful

I was recently in Europe, and wanted to get this book to help translate. The dictionary component is grouped into different categories though, so it was difficult to find the words when you needed to do so quickly. There were also a lot of words that it didn't seem to have the translation for (or at least I didn't find it in time). As such, it ended up not being very helpful in the moments that I had wanted it for (e.g., trying to figure out what to order at a restaurant, etc.).
