Hi there! I'm searching for a relatively cheap Portuguese restaurant here in Cambridge, do you have any recommendations?
The Nandos City Centre has some excellent food and is located in the centre of town if you are interested. Would you like me to book a reservation for you?
No, I would like a place that's in the south part of town. Is there one of those?
There is another Portuguese restaurant in the south part of town called Nandos, would you like a reservation there?
May I have the address and postcode of Nandos, please?
Certainly, Nando's address is Cambridge Leisure Park Clifton Way cb17dy. Can I book this for you, and if so how many people will be dining?
Can you help me find a train out of Cambridge?
Sure, could you provide what destination you're looking for and which day you'd like to depart on?
I would like to depart on Monday and head to Birmingham. 
I'm sorry, but my system is experiencing an error. Can you please restate your train requirements? Thanks.
Actually, I need to leave from Cambridge Saturday after 09:45 and go to Birmingham New Street. May I have the arrival time, train ID, and price, please?
We have 14 entries that match your criteria. Do you have a preference there?
Could I have the arrival time, train ID and price for a train leaving as close to 0945 as possible
The TR7683 train leaves cambridge at 10:01 on saturday. It arrives at birmingham new street at 12:44 and the price is 60.08 pounds.
Okay thank you! That's all I need today.
