Example conversations

One way of how a pizza can be ordered is by classical slot filling, where the bot guides the user to the next slot to be filled:

User: I want to order a pizza

Bot: Which crust would you like? Italian/thin or American/pan?
User: Italian, please.

Bot: Which toppings do you want on your thin pizza?
User: I'll take ham and mushrooms.

Bot: So, I have a thin pizza with the following toppings: ham, mushrooms - Any other toppings you would like to add?
User: No.

Bot: Alright, thanks for your order. We are now preparing your thin pizza with mushrooms and ham.

However, the user does not need to wait for the bot prompting for information: all information can be given when it suits the user best, just like in a human interaction. The bot will listen for the crust type and up to 4 toppings and store them:

User: I want to order an American pizza with cheese, onions, and pepperoni

Bot: So, I have a pan pizza with the following toppings: cheese, onions, pepperoni - Any other toppings you would like?
User: I'll have some mushrooms as well.

Bot: Ok, I have updated your order. So, I have a pan pizza with the following toppings: cheese, mushrooms, onions, pepperoni - Any other toppings you would like?
User: No

Bot: Alright, thanks for your order. We are now preparing your pan pizza with cheese, mushrooms, onions, pepperoni - Enjoy!

Finally it is possible to not only add but also remove toppings:

User: I want to order a thin pizza with broccoli, mozarella and salami

Bot: So, I have a thin pizza with the following toppings: broccoli, onions, mozarella, salami - Any other toppings you would like?
User: I'll have some bacon instead of salami and remove the broccoli please.

Bot: Ok, I have updated your order. So, I have a thin pizza with the following toppings: bacon, onions, mozarella - Any other toppings you would like?
User: No

Bot: Alright, thanks for your order. We are now preparing your thin pizza with bacon, onions, mozarella - Enjoy!
