Find me a restaurant that serves belgian food in the centre
I'm sorry, there aren't any.
How about one that serves Turkish food?
I have three Turkish restaurants. Two are moderately priced and one is expensive. Any preference?
I would like to know the price ranges of the 3 if possible please, and also would like to dine in the centre of town.
The Meze Bar Restaurant is expensive. The Anatolia and Efes Restaurant are both moderately priced. They are all located in the centre. 
Thanks, I'm also looking for a train that goes to Cambridge on Saturday. 
There are many trains that meet your criteria. Would you like to narrow it down further by departure time or arrival time?
I'd like to arrive by 21:15 please! 
Sorry, I need an origination point to give you that information.
The train should depart from ely and should arrive by 21:15.
The TR4288 train arrives at cambridge at 19:52. Can I book it for you?
Not right now.  Thank you.
Do you need anything else?
That is all I need.
Ok great, have a wonderful day.
