The key focus of this design is efficiency. If a user has few/no restrictions, a random item is likely sufficient. This design also promotes exploration, because it is an easier task to decide if one likes an item than to choose from a set of items. In this design, a random menu item is generated, along with its ingredients. If the item is good, the user can settle with this item. However, if the user cannot choose this item, he can tell why such item is bad (contain restricted items from his diet, does not like chicken, etc). Based on the additional information, the interface suggests a new random item that meets these requirements. Again, the user can add more requirements, to refine the suggestions by the system.
Pros:
- Easier for patron to decide, not overwhelmed with information
- The patron can literately refine his restrictions, depending on the item suggested
