If you are in a rush and want to learn how to say "Where can I find a good restaurant?" this is fine. It is, however, riddled with errors that will throw the beginner off track. A serious student will not get a solid foundation with this course. If you have the time and are dedicated to really learning Portuguese, get the real thing - Mastering Portuguese.
