This is an awesome coffeetable book! All the little things you wondered about how cities work, from electricity to sanitation to how the milk arrives, are covered in depth with tons of pretty pictures.
It's tough not to get sucked into this awesome urban adventure.
Neato-s! Once took a tour of Parisian sewage by mistake. Was looking for "les catacombs" and the taxi driver took me to "les egouts" since he didn't know what the catacombs were and I explained it as "underground tunnels that were dug long time ago".
Must admit, have a serious appreciation for the sewage and other related non-glamourous logistics matters since.
