I'm looking for a train. I want it to go to Stevenage and leave from Cambridge. There are many trains available. What day and time do you want to travel? It should leave after 18:30 on Saturday. I have a train leaving at 19:21, is that okay? How long is the trip and when will I arrive? Also need to know the price. The trip lasts 49 minutes and is 12.8 GBP. Okay, thank you for that information. I also need to find a cheap restaurant. We have many available. Do you have a certain type of food you would like?
