I need a train to leave from cambridge after 15:30. Ok, lets get you set up, where are you going and on what day? I will be leaving on saturday and going to london liverpool street. I would recommend TR4859 which leaves Cambridge at 15:59 and arrives at London Liverpool Street at 17:27. That sounds fine. Can you reserve 6 tickets for me please? You're all booked. TR4859 for 6 people will be 79.67 GBP. Your reference number is CTETVS75 . Is there anything else I can help you with today? I am looking for places to go in town. The attraction should be in the type of museum There are 23 museums in cambridge. Are you interested in a particular type of one in a certain part of town? Not really. Pick the best one for me! I am very partial to the Cambridge Artworks museum located at 5 greens road and admission is free. Does that sound good? That sounds great! What area and can I get the postcode? It is located in the east and the postal code is cb13ef.
