There is consistent proximity throughout the logotype. The negative space forming the "N" makes sense with the name because looking at the logotype engages the audience when locating the "N". I also think the logotype font works well bold.
This logo is very clever. I love the fact that a bar code makes the shape of a beer mug. It is funny to me to see. I am not sure what kind of company this is for, other than some kind of beer company or bar. It is eye catching and clever.
