Can you tell me if there is a restaurant named Kohinoor in Cambridge?
Yes there is one listing, it serves indian food,it is in the centre,and has a cheap price. Would you like me to give you the information?
Just go ahead and book a table for 7 on Saturday at 12:45 please.
I apologize, I am unable to book at that time. Is there another time you'd like me to try for?
11:45 will be Ok.
I found Indian restaurant called Kohinoor 74 mill rd ,which is in center . Is that good for you?
Yes that is perfect. Can I get the reference number please?
The reference number for your reservation at Kohinoor is HB7JSPFK. Your table will be reserved for no longer than 15 minutes. 
I also need to find a 4 star guesthouse that is located in the north, can you help me book one please?
Avalon has good reviews and is in the moderate price range would you like to book that?
Can you let me know whether they have free parking and what the postcode is?
Sure, the Avalon has free internet but no free parking. The postcode for them is: cb43pd. The archway house has both free internet and free parking.
Thank you for your help!
