Allows a restaurant to upload daily specials to the menu listings.
Pros:
- Devotes large amounts of space to the primary 'target' of the UI, the food itself.
- The single window design also has an affordance to upload food items to the server/database using a GUI window devoted to the task.
- This menu presentation also highlights food specials with a border and food that are suitable with a substitution with a border.
- Menu items that are sorted to show specials first, regular menu items second, and restricted items with substitutions last.
- Pictorial representations of restrictions and menu items are shown in a format discernible to all languages.
...
Conversely, selecting a preference or restricting the ingredients filters and re-orders the menu items, reflecting the user's choices.
Pros:
- High level of feedback between the interplay of food versus ingredients.
- Learnability is very high because menu and food items are shown simply.
- High level of language independence with large picture icons

The flow here is designed to be similar to a shopping cart, with entering of dietary restrictions and preferences kept separate from food selection. We also provide here a 'summary' view at the end so that users can view all the food that they have chosen and see the total price. We also use text entry as opposed to pictorial selection to choose allergens/preferences.
Pros:
- Text entry obviates the need to hunt through a list of pictures to find their allergens/preferences
- Save user profile allows for tracking of preferences over time.
- Many opportunities allowed to fix an incorrect entry for a safer design. For example, the user can remove items from the queue on the "checkout" screen.
