I am looking for a train leaving on Saturday. There are several trains leaving on Sunday. Do you have a departure/destination in mind? The train should depart from cambridge and arrive in standsted airport. I have 19 trains leaving Cambridge for Standsted on Saturday. Did you have a particular departure time in mind? I don't have a departure time in stone, but I need to arrive by 17:15. The TR2001 is the last train of the day and arrives at 17:08. The train before it is TR0638 and arrives at 16:08. Do you want me to book one for you? Yes, please book the TR0638. I need 7 tickets. Your tickets are reserved. That reference number is 6J063KBL . Alright, since I'm going to be in the city centre for awhile, could you tell me of any interesting places there? There are several beautiful churches near the centre, all well known and valued for their beautiful architectural styles. Is that something you might be interested in? What's your favorite one? I trust your judgment - let me know the best one's address, postcode, and attraction type, please. I would suggest All Saints Church for it's amazing architecture type. It's address is on Jesus Lane with a postcode of cb58bs. Make sure you check out that stained glass!
