I have 202 trains departing from Cambridge. Where are you headed and when do you need to arrive? TR9291 leaves at 14:01, shall I book you? I successfully booked you on the TR9291. Your reference is WGWRLL09 and the total fee of 42.96 is payable at the station. Is there anything else I can help you with? We have many restaurants to choose from. Do you prefer a certain type of food?
I'm looking for a train that departs from Cambridge on Sunday. I need to go to Broxbourne, and I need to leave after 13:45. Yes, and my two companions, please. Yes, I'd like to find a restaurant in the centre area also. I'd like it to be vegetarian, and I'm looking for something expensive.

I'm sorry, but there are no exclusively vegetarian restaurants anywhere in Cambridge. You may want to try one of our many fine Indian restaurants, as they'll have vegetarian dishes.
