Hi, I'm Mark. My friend John and I want to organize a birthday party.
At what venue would you like to have your party organised?
John suggested North Heights Venue because it's nice. 
On what day would you like your party organised?
Thursday please.
When would you like your party to kick off?
at 3pm. I would like to know the weather if that's not too much trouble. I want to throw a party outside.
It will be Raining all day on Thursday in Pittsburgh, with temperatures of around -3 degrees celsius.
Oh no. Well I guess we'll just book the venue then. Afterwards I think we'll eat out though. Can you find a restaurant nearby?
Unfortunately there are no forecasts that match your search. Would you like to change any of your criteria?
I would like to reserve a restaurant, can you find one near the Center of town
Sorry, I did not mean to do that. I found the Tamarind, it is located in the Center of town and is open from 9 am to 5 pm and servers Burgers.
Can you find one that serves pizza please?
Okay, I found the Legume. It is open from 6 am to 4 pm and is expensive.
Anything for my bestfriend! Can it accommodate for 55 guests?
It has a max party size of 25.
Oh no, well, if it's not too much trouble, can you find a different restaurant?
None of the restaurants in the database can accommodate more than 50 guests.
Okay, I'll just take the previous one. Thanks!
For what time should the reservation be made?
6pm
I am sorry, but the reservation request was not successful.
7pm?
I am sorry, but it looks like the restaurant is not able to accomodate you.
Any time will work, I didn't plan doing anything else that day.
I have confirmed your reservation at Legume for 3 pm.
Thanks that's all!
Thank you and goodbye.
