I need a zero star hotel in Cambridge with wifi.
There is one hotel with your criteria. cityroomz in the centre. It is moderately priced. Would you like me to book it for you?
No, I actually need it in the north part of town.
I have no hotels that match what you want in the north area
I guess the Cityroomz in the centre would be fine then.  Does it include free wifi?
Yes, it includes wifi
Can we book it for 8 people starting saturday?
How many days will you be staying? 
I'll be there for 5 nights.
Booking was sucessful! Your reference number is U87HN6I5.
I'm also looking for an inexpensive Italian restaurant in the same area.
I have the Da Vinci Pizzeria. It's a cheap restaurant in the north. Would you like me to help you reserve a table? 
Yes please. For the same amount of people on the same day at 14:30.
You're all set for saturday at da vinci pizzeria at 14:30 for 8 people.  Is there anything else I can help you with?
Is there a reference number for the Pizzeria reservation?
yes your reference number is 98842, is there anything else I can help you with today?
No, that's all I needed. Thanks and bye!
Well, you're welcome!  And you have a great day!
