I am looking for information in Cambridge
I need some more specifics to help you.  What type of information do you need?
I am looking for a guesthouse in the north. I would like it to be expensive and include free wifi.
I was unable to find any matching places for that.
What about one in the moderate price range?
Yes I have 8 guesthouses available in the moderate price range.  Will you require free parking and wifi?
Yes I do need the free wifi.
Might I recommend the Acorn Guest House? It meets your criteria. Would you like to make a booking?
Yes, that would be good. Can you just let me know the star rating of the hotel, whether they have free parking, and address? Thanks
Sure! the acorn guest house is a 4 star hotel with free parking and the address is 154 chesterton road.
I also need to find a train for Friday going to Cambridge from Norwich and leaving after 15:15.
TR8365 leaves norwich at 16:16 and will arrive in cambridge at 17:35. Would you like me to book you tickets for that train? 
No need to book the tickets I just needed the info. Thats all I needed thanks
Can I help you with anything else?
No, that will be all. Thank you!
You're very welcome! Have a great day!
