The advertising agency's office offers Xbox 360, Wii and PlayStation 3 for employees to relax, as well as an on-site cafe with three flat-screen TVs.
There is a private room for nursing mothers, on-site yoga and cardio classes, and women's and men's locker rooms and showers. There is also a beauty room for massages, manicures, pedicures, haircuts and more.
Why would anyone leave this office? Hill Holliday is located in the Fanueil Hall/Quincy Market area of Boston and was designed with the objective of "open space" -- hence very few walls and a lot of glass.
