Crous - libre service Champollion is a self-service restaurant in the Latin Quarter of Paris's 5th arrondissement that serves student meals. Diners can choose a set meal, sandwiches, or fruit, yogurt, and fruit puree, and the vegetarian sandwich contains a lot of mustard. While the kitchen is being repaired, food is served in containers and reheated by customers in a microwave. On days when fruit, yogurt, fruit puree, and the set meal or sandwiches are unavailable, it is difficult to assemble a complete meal.
