I am looking for the Nusha. Can you help me?
Sure, that is a fun entertainment venue located at Unit G6, Cambridge Leisure Park, on Clifton Road.
what is the fee ?
Unfortunately, they often change so we do not have that information. But I can give you their phone number. It is 01223902158. Can I assist you with anything else? 
Thank you. I also need a book a train, leaving cambridge after 21:30.
Ok and what is your destination?
I want to go to London Liverpool Street on Friday.
TR9557 leaves at 21:59, or, if that is too close to 21:30, TR3138 leaves at 23:59. Do either of those options work for you?
Yes, can you give me arrival times and prices, please?
Yes the train arrives at 23:27 and the price of the fare is 16.60 pounds.
Thank you goodbye
Have a great day.
