Overall, Nasty Cookie is praised for rich, warm cookies, creative fillings, and eye-catching packaging. Reviewers describe soft, gooey interiors with crispy edges and memorable flavors, especially chocolate chip, s'mores, and red velvet. However, many note high prices and small cookie sizes, with mixed service experiences—some friendly and helpful, others rude or inattentive. Outlet atmosphere and seating vary, influencing overall satisfaction despite strong product quality.
