I'm looking for information on 4-star rated guesthouses in Cambridge
I have a number of 4 star guesthouses available, would you like to book one in a particular area?
Not really. Could you suggest one with free parking?
Okay, how about the Acorn Guest House in the north? 
Sure.  Can we spend 5 nights starting on Sunday?  I am going to need room for 7 people.
Reference number is 29IN9CT3 for the acorn guesthouse. 
I would also like to eat somewhere cheap in the middle of town. 
I suggest the dojo noodle bar, an asian oriental restaurant, would you like to make a reservation?
do you have one the is portuguese food ?
There is. How does Nandos City Centre sound?
Sounds great if it is portuguese. I'll take a reservation for 7 people at 20:00 for the same day. 
You're all set. Your reference number is 6R5W1RRE and your table will be reserved for 15 minutes. Anything else?
No, that's all I needed today. Thank you for your help! Goodbye!
Okay, it was my pleasure to assist you! Bye!
