Thank you! I am looking for a cheap restaurant.
Okay, I recommend Zizzi Cambridge. Would you like a reservation?
Yes, please. It needs to be for 4 people at 18:15 on Thursday. 
I was able to book your table successfully. Your reference number is T8HBG78O and your table will be held for 15 minutes. Do you need any further assistance today?
Well, I also need a place to stay.  I prefer a guesthouse with a 2 star rating.
We have many guest houses, but none of them have a two star rating. Could I find something else for you?
Yes you can The hotel should be in the same area as the restaurant
I would suggest the acorn guest house.
Okay thank you. Please book that for 4 people at 18:15 on thursday.
I will book that for 4 people.
Thank you. What is the address?
The address is 154 chesterton road.
I need a cab to commute, to the hotel by 18:15 and I need the contact # and car type too please
Okay! From where will you be departing?
Actually I will be departing from the hotel and arriving by the 18:15 restaurant booking.   How silly of me to tell you that I was leaving the restaurant. 
Your taxi is confirmed. You should look for a white lexus. If you need to contact the driver, the contact number is 07179268142.
That is all I need today thank you. 
You're welcome. Please contact us again if you need any further assistance.
