Couple things…
*Most of the rotating “hot” meals are quite good and there are multiple choices regarding hot dishes. D feels like the options that are always available (salad bar, sandwich bar, panini maker etc.) work well if you don’t like the hot choices. Of course some meals are better than others, and some meals can get boring, but overall she is really happy with the quality and the choices.
*Lots of ingredients are sourced locally when possible (in season) including produce from Midd’s organic farm
*They have two main dining halls that serve breakfast, lunch, and dinner. A third dining hall is open for breakfast and lunch, and occasionally special dinners. It is on its own menu system so lots of kids choose to go there when they serve a popular dish.
*Dining staff is happy to make recipes that kids bring from home 
*Unlike many peer schools, Midd doesn’t have a meal plan which means there are no points or swipes per meal. The dining halls are open all day and kids can come and go on their own schedule as many times as they want. Some kids even like to meet and study in the dining halls.
