I'm looking for a cheap Italian restaurant. 
How about Pizza Hut City Centre?  I hear it is very good.
I s it located in the north?
No, that one was in the Centre.  But, da vinci pizzeria is in the north
Da Vinci Pizzeria is fine can you book a table for one for Monday at 12:00?
I will book it for you,is there anything else I can do for you ?
Yes, what about the reference number?
My system is down and I am unable to book at the moment.  Here is their # 01223351707 or we can try again later.  Sorry for inconvenience.
Wow, really? Could you try again please?
My apologies, this is actually a system issue and i cannot book.   I have reported in, in the meantime do you need other information?
I will try back later for the reference number. Could you find me a place to stay that is near the restaurant?
There are several in the moderate to cheap range. Do you have a star preference?
no stars would work for me. 
I would recommend city centre north b and b. Would you like me to book that?
Is that a guesthouse with 0 stars?
Yes they are a guesthouse with a 0 star rating in the north area.
Okay, great. Please book that for me then. It'll be 1 person for 2 nights
What day will you be arriving?
I will be arriving on Monday.
You are booked into city center north b and b with reference number O1TNBPLU. You are also booked  at da vinci pizzeria, reference number QLKCDA7V.
I also need a taxi to get me from the hotel to the restaurant by my reservation time.
