Not sure what your question is about the dorms? The quality of the space itself? The feeling about living there? The dorms physically are fine. Some are older, some are newer, but they all offer a reasonable amount of living space, a closet, a central lounge and kitchen (some dorms have more than one lounge in the building). Bathrooms are shared in the hall. Each floor votes on whether or not to have bathrooms gender-neutral. If even one person prefers separate male / female then that is the way they are. There is also gender-neutral housing available. There are some themed housing available too for later years. These are small houses not dorms per se, but they are college sponsored.
Grinnell groups all class years together. Some schools have dorms reserved only for first-years. In my son’s first year, it happened that his floor was all first year students. But that is not always the case. In his second year, his floor was primarily second-years with a few first-years. Those first years became good friends with my S and his friends who lived on that floor.
There are Student Advisers in the dorms,and Residence Life Coordinators (who are paid, and who i believe live in one dorm but have responsibility for a group of dorms?). Anyway, these people are all great resources if you want help or advice. I believe but not positive that they also may coordinate some dorm activities.
Also, while people may socialize with friend groups in their dorms, any events or parties that use campus facilities technically are open to everyone. At least that’s what i remember my son saying. So, unlike other schools that may have frat parties that are or feel exclusive, Grinnell has a weekly themed party for all students. My S doesn’t like big parties and so he doesn’t go to those, but that doesn’t mean he is left out of social life – he hangs with friends, attends other events that are of interest, etc… He does attend the all-campus parties like 10/10 and Block Party. Some kids who have recently graduated even come back for those!
As for the food: i think it’s quite good! Certainly, there are a variety of stations at every meal: grill, pizza, pasta, stir fry, salad bar, vegan, Halal, etc. etc. There is a soft ice cream machine, a variety of desserts. I think they also have bread, pb and j, (maybe even cereal?) available all the time, too. The school is making an effort to locally source as much as possible. In all our college visits, there was only one school where the food wasn’t good, so i wouldn’t be concerned about this really.
The Grinnell Dining Hall is an amazing space. Big windows, a variety of seating options – long tables, private booths, some private dining areas that are used for meetings. This year, they instituted a new all-day access to the dining hall, where certain food stations are open all day. The D-Hall used to be open only during specified meal times. Also, there is a snack bar: again another nice place to be. There is a cafe run by students, too – this has limited hours; i’m not so familiar with it.
