Densha Ottoko filming locations?

I am getting ready to return to japan for the third time and since my last visit watched and very much enjoyed DENSHA OTTOKO. I was wondering if anyone could post maybe simple walking instructions to some of the more well known shooting locations in Akihabara? There is a web site with maps but my computer is having trouble displaying them and they are a bit hard to understand.

I was most interested in
Solder building and anything else you might know about related to the show?

also maybe directions to Shinjuku monolith.

Very sorry for so many questions but I am excited to see a few of these places!

Thanks very much!

also maybe directions to Shinjuku monolith
Shinjuku Monolith is in the high-rise district of the west side of JR Shinjuku station, at the back of Keio Plaza Hotel.

thanks very much!

Which part of Densha Otoko had him going to the Shinjuku monolith?

I may have read the site wrong but It said that is the first place they meet for their date when Densha is picking the clover wondering if Saori will show up or not is that location.
