I need to catch a train out of Bishops Stortford, to arrive by 20:45. There are many trains. Where is your destination? What day would you like to travel? Cambridge on saturday. I have the TR7734 leaving at 19:29 and arriving at 20:07. Would you like me to book that for you? Sounds perfect, but I don't need it booked just yet. What's the price on that? The price is 8.08 pounds. Is there anything else I can help you with? Thanks. Yes, I am looking for a particular attraction. Happy to help. What is the name of the attraction you are interested in? It's called St. Catherine's College. What's the fee to get in there, and is it a college, architecture, or what? It is free. Is this attraction an actual college still or are the buildings just there for architecture? It's of the type of college. Can I help you with anything else?
