You can view it on your smartphone, but it was helpful to have a paper map to see the whole picture when going to a place I'm not familiar with. Especially bbcom, it was easy to choose which shops were good and to make reservations. I was able to find a great shop. Please use it for preliminary research before your trip. The latest ones were also available at the entrances of airports and hotels. This one was the latest for January. It's unused, but there are some minor folds.
