The school canteen works between 11:50 am and 2:10 pm. 1 100 meals are served each day, including 235 meals for boarders dinner. Since january 2019, Ste Marie du Port High school works with the catering company CONVIVIO. The chief Florent HERVÉ (with Ingrid FRIETMAN, Aurélie VINCENT and Geoffroy VINCENT), provides meals using local products. We try to provide organic food as far as possible and a nutritionist watch if the meals are balanced.
