I think the question of one dining hall vs more than one is such a good point. My student at Bates loves the central dining room as it is such a hub of activity on campus. It’s that way at Vassar also and I only hear positive things. At Smith College, where I also have a student, they have decentralized dining and use that to accomodate different preferences like gluten free, vegetarian etc. but I think it is actually seen as kind of a pain and students would prefer one dining location. It’s complicated at Smith because food service workers are unionized (this is a good thing).
