Case Studies Number Ten--subway.com:Architecture

The site does not appear to have a deep architecture. It does not have a site map for me to look if there are a lot of pages, but I can tell from the primary navigation system and other thing that this site does not have lots of pages.

The architecture is not flat and additional navigation / links appear as I go to further levels in the site. I think it is a good thing but also a bad thing. Good thing is these additional navigation can provide users more information and choices about any sections. Bad thing is they may confuse users what to follow or where to go next.
