I need an expensive restaurant in the centre 
Sure, what type of food do you want me to look for?
I don't have a preference. It should be in the centre, however.
bedouin is a very nice african restaurant. Shall I book it ?
Yes, please.  Would you book it for 8 people on Tuesday at 13:00?  I need to be sure to get the reference number, please. 
Booking was successful. The table will be reserved for 15 minutes. Reference number is : P29I9V5T.
Thank you. I'm also in need of a place to stay. I'd like it to be a hotel with a star of 2. 
There is the Ashley Hotel, which is a two star hotel in the north. Shall I book it for you? 
Does the hotel have free parking?
Yes free parking and internet. Would you like me to book it for you?
Yes please for 3 nights for 8 people on Tuesday.
You are good to go, in case you need it, the reference number is FBC4YKK9, can I help with anything else?
No, that is all.  Thanks for being so helpful for my upcoming trip.  Looking forward to my stay.  Bye.
Your welcome, I'm glad I could help.
