The Restaurant lesson is in general only for non-food and non-drink items related to a restaurant (e.g. knife/fork/spoon, serviette, tablecloth, chef, table, chair).
There are only a very few food items which are also included (e.g. salt/pepper, water, wine).
In general though, all foods and drinks should rather go in the relevant food/drinks lessons: e.g. Food, Fruit, Vegetables, Drink.
