Within these upscale supermarkets, young cooks ages 4 to 6 work from menus that include easy lasagna roll-ups with meatballs and mix-in-the-pan chocolate cakes, while kids ages 7 to 11 make meals like spicy Mexican salad with warm sopapilla cheesecake. Teens grill, bake, and make pasta from scratch. All can conduct gastronomical investigations in food science classes. Classes start at $30 each. Multiple locations.
