Hi, I'm looking for information on booking a train. I would like to leave on Wednesday and arrive at the destination at 17:00. 
From where would you like to catch the train and what is your destination?
I would like to catch the train at London Liverpool Street and I'm going to Cambridge.
the TR2826 arrives at 15:07. would that be ok?
Yes can you book it for me and give me a reference number ?
Yes of course. Your booking number is DQRT2P5U.
Awesome. I also need a place to eat in the moderate range. I'm thinking maybe in the city centre.
There are 5 moderately priced restaurants in the centre, 4 serve british, and one serves asian oriental food. Which would you prefer?
I really wanted a moderately priced restaurant in the center that serves spanish food actually
I found la tasca it meets your criteria would you like me to book that for you?
Just give me the address if you could please
The address is 14-16 Bridge Street.
Thanks, I don't need any more help. Have a good day!
Thank you! And enjoy your stay in Cambridge!
