I am looking for a restaurant in Cambridge called the La Margherita
I have found the one you are looking for, the address is 15 Magdalene Street City Centre and the phone number is 01223315232.
Okay, great! Please book me a table for 6 at 14:45 on Sunday. Please provide the reference number as well.
I'm sorry, there are no spots available on that day and time. Is there another time or day you would like perhaps?
Well I'm also looking for a train.  Can you coordinate a time with a departure from cambride on sunday?
Sure, where would you like to go?
I would like to depart from Cambridge this Sunday and arrive at London Liverpool Street by 12:15
The TR0995 arrives in London at Liverpool Street at 11:27 on Sunday. How does that sound?
Thank you for the information that's all I need today. 
Thank you, enjoy the rest of your day.
