As for me - the best I’ve experienced were at Florida Tech (on visit day) and Colorado School of Mines…although the students there said it was only that day that families were there.
My kid went to Santa Clara. They only had one main dining hall but it had a bunch of different stations. Lots of choices. Lots of farm to table, and locally grown options.
There was a terrific coffee shop/breakfast place with great pastries and teas, coffee, juices, yogurt, etc.
In addition, the “meal plan” was totally points, not per meal. So you only paid for what you actually ate.
Food quality was excellent. Climate was very mild and there was a huge outdoor patio area too.
I’d be interested to find out, but best means something different to everyone. We would be looking for organic and heavy on vegetables and fiber with gluten and dairy free options. I wish I could say that we were just being picky, but we are actually dealing with an unknown digestive issue and have not been able to find a diagnosis from the GP the gastroenterologist or the naturopath…plus a rheumatologist and dermatologist, so we just try not to poke the bear.
St. John Fisher in upstate NY has great food! and a nice dining hall IIRC. It’s pretty small, so not as many options, but a great less-competitive option for someone wanting good food and lots of merit aid.
