MORALE FACILITIES
USS Hiroshima's morale facilities are in place to provide recreation and respite for the entire ship's complement and guests. We have The Sake Bar, a Japanese-themed sushi bar, wet bar and restaurant, to provide a place to unwind, as well as a convenient alternative to the ship's Mess Decks. For more exotic excursions, the ship's holodecks are available. Finally, multiple gymnasiums are provided to give the crew ample opportunity to work on physical fitness.
Where we live:
Most of the officers and crew on USS Hiroshima live in the saucer section, leading to the rounded look of the main passageways. The sectored shape of quarters does present some decorating challenges, but innovative people tend to find ways to make them feel like home, despite the difficulties.
Junior Officer Quarters: Since, even on a large ship like USS Hiroshima, space is at a premium, junior personnel end up with the smallest living spaces. As such, one of the rewards of advancement is often to move into better quarters. While junior officers have adequate living space, few view the accomodations as luxurious.

Senior Officer Quarters: Larger floor space and beautiful vistas are the purview of senior personnel, including department heads, assistant department heads and certain principals.

The Sake Bar:

In keeping with the motif of USS Hiroshima, the newly-remodeled Sake Bar is a Japanese-themed bar and restaurant. With three completely different sections, as well as a night club, it is designed to accommodate a variety of tastes.
Dining: The formal dining area allows members of the ship's complement and guests to 'get away from it all' and enjoy a lovingly prepared meal in an environment that feels anything but like that of a starship.

Bar: The bar is where personnel can unwind and share a drink or two with friends. It is a place for bonding and for escaping the feeling of being on the ship.

Informal Dining: For those who wish for a quicker dining experience in a relaxing setting, The Sake Bar offers a full-service sushi bar, complete with Japanese-style trimmings and a built in miniature aquarium.

Holodecks:

Fully customizable, Hiroshima's holodecks provide the opportunity to interactively explore new situations and events. Integrated replicator systems provide realistic food and beverage, as well as other tangible sensory stimulation, while programs are either saved to the main core or brought via isolinear chips.
Note: Only holoprograms that meet the conditions and requirements of Starfleet Regulations are permitted. Violators are subject to disciplinary action.

Holodeck Technology (how it all works), courtesy of LCARScom.net:
The basic mechanism behind the Holoscene is the omni-directional holo diode (OHD), a microminiature device that can project full-color stereoscopic images and force fields in three dimensions.
The walls of a Holoscene are covered with millions of OHD's, under dedicated high-speed computer control.
OHD's manipulate tiny and subtle force fields, allowing an individual to "feel" projected objects that are not really there.
Other (inanimate) objects can be physically created by replicator matter conversion.
Shaped force fields and background imagery allow a visitor to experience volumes and distances apparently larger than the Holocene room could physically accommodate.
Force fields create a "treadmill" effect, so a user could walk or run over seemingly great distances while the projected scenery scrolls by.
