Hi I would like to organize a birthday party.
Sure. May I have the venue and host name, day, start time and guests number?
North Heights Venue, 21 guests, for Sunday at 6pm.
May I have your name, please?
Mark
OK, the North Heights Venue would be happy to accommodate you on Sunday @ 9 pm.
Can I book it for you now?
That's great. I was wondering if the weather is going to be nice that day, I would like to do the party outside.
Let me know if you would like to reserve the venue. In what area would you like the weather?
Chicago please. I would also like to find a restaurant if the weather is bad.
It will be Snowing all day on Sunday in Chicago, with temperatures of around 28 degrees celsius.
okay well lets reserve a restaurant then. Preferably in the east of town.
I have Cactus Club, in the east, that serves steak, with a cheap cost and is open 8-10. 
Sounds good
Would you like to search for any more restaurants?
No that's okay. I can't wait for this party!
Is there anything else that I can do for you?
Oh I about forgot, I don't want Chinese food.
This restaurant serves steak.
That's perfect then.
Would you like to reserve?
yes please
I am sorry, but the reservation request was not successful.
