Attention this little book will not give all the necessary, but it still offers a nice overview for travel and not be totally lost up there. Everything is classified: presentation, current dialogues, accommodation, some grammar too ... the book is aptly named "Travel Book" by cons not hope to know everything about Bokmål. To really go seriously, you better have beside the Norwegian editions of Assimil + cd to properly learn how to pronounce this beautiful language, and be more comfortable.
For my case this little book helps me especially draw in, because the format allows it to take anywhere. If left clinging to have enough level to get by, and definitely from this dreamland!
