Can you help me find a moderately priced restaurant that serves North American food? Thanks.
Unfortunately, I am unable to locate a moderately priced North American restaurant. I did find an expensive one, would you be interested in that?
No. How about Italian food?
Sure.  There are five moderately priced italian restaurants.  Would you prefer a certain part of town?
Perhaps the center? But I don;t think I have a preference.
Pizza Express is a great place that serves moderately priced Italian in the city centre. Would you like me to make you a reservation?
Yes. Please reserve for 5 people on Sunday at 15:00. 
I was able to book for you. Do you need a reference number?
Yes, I do need it.  I'm also looking for a train that goes to Leicester after 18:30.  Is there anything available?
What day do you need to leave?
I need to leave on monday and depart from cambridge. 
There are 5 different trains on that day. Would you like me to book one of them? 
Yes please. I just need tickets for all 5 of us. as close to 18:30 as possible.
the train id is TR0335. Booking was successful, the total fee is 189 GBP payable at the station .
Reference number is  : 13V7H457.
Thanks that's all I need today
