I am looking for a place to dine. The restaurant should be in the expensive price range and should be in the south of town
I have 2 chinese, indian, italian and mexican food. Did you have a preference?
Yes, I prefer italian. I really like pizza. 
There is one Italian restaurant in the south. It does have an expensive price range. Not sure if it serves pizza though. Would you like the phone number?
Well let's change that to Mexican and I need a reservation for 2 people at 16:30 on Sunday.
Okay, I have you booked at Chiquito Restaurant Bar then. Reference number is : 6OG10PUW.
Ok, thank you.
Is there anything else I can help you with?
Yeah, I'm also looking for a hotel called the allenbell. 
Sorry I dont have anything with that name.
are you sure? i was literally there 3 weeks ago...
The allenbell is not available.
why is it not? it is there please look again.
I have checked again. The hotel is listed as "Allenbell" instead of "The Allenbell." Would you like to book a stay there?
Yes, I need reservations for the same group of people on the same day as the previous reservation. We will be staying 4 nights.
How many people and on what day was your previous reservation? 
2 people on Monday is what I would like.
Ok.  I apologize for the confusion.  I booked the room for you and the reference number is DAQEE9BH.
Thank you, that is all that I need.
Thank you for the Cambridge TownInfo centre. Goodbye
