All of the sorority/fraternity houses on our campus had a kitchen staff and a janitorial staff. (In our house, the janitorial staff consisted of two maids...then, in the kitchen we had one lady who was the main cook, & she had 2 assistants. One of the assistants was a man who also did some handywork around the house and did things like take out the trash, etc.)
We were offered 3 meals a day, 5-6 days a week. The cooks also made food for our pre-football-game brunches and homecoming and parents day lunches (and any other special events we asked them to cater). The meals were included in the house bill. Breakfast was optional for people who lived off campus. Everyone paid for lunch & supper whether they ate there or not. If you had a class or something at night, you could request a "late plate" and the cooks would make you a take-out version of that night's dinner in one of those divided styrofoam plates and write your name on it.
We also had a fridge downstairs that was open to everyone and had juice, tea, milk, etc. and a cabinet with cereal, pop tarts, granola bars and the like. Plus, the cooks would often make little treats for us and leave them in the dining room. The food was pretty good and there was a nice variety. I've heard it's even better now because there's a new housemother and a new cook. I think the cost was comparable to the school meal plan.
