U: I need to take a train from cambridge on saturday.

S: There are 202 trains that fit that criteria, whats your destination?

U: I am going to stansted airport on saturday and need the train to leave anytime after 15:30 please

S: I have train ID 2001 leaving at  16:40 arriving Stansted Airport at 17:08.  Would you like me to confirm this for you.

U: Before I book this, what is the price?

S: The price is 8.08 pounds. Would you like me to book it?

U: No I'm not ready to book a spot yet. I do need to find a place to eat in the west though.

S: There are 14 restaurants in the west. Is there a particular cuisine you are looking for?

U: I would like an indian restaurant.

S: The tandoori palace has Indian cuisine. Would you like me to book a table?

U: Yes I'd love one, please. Just me, and I'd like to eat at 10:15 on the same day.

S: I apologize, the booking for that time slot was unsuccessful. Would you like to book for another day or time?

U: How about 9:15?

S: They are not open that early, can I try another time?

U: Sure. Are they open at 11:15?

S: I'm sorry, that time didn't work either, would you like to try something else?

U: Sure. Please try 10:15 on the same day. I would like the reference number, please.

S: I'm sorry, neither 11:15 nor 10:15 are available at Tandoori Palace. Would you like to try a different restaurant, maybe Meghna, an Indian place with a moderate price range?

U: Yes, please book Meghna for 10:15, same day.

S: Unfortunately, there are no bookings available for that time. Would you like to try a different time or day?

U: I would really like indian food on saturday in the west area. If you can book it for 1 person at 10:15 or 9:15 I don't care which place.

S: I booked India House for 1 at 9:15 on Saturday, reference number XWR84US7. The restaurant is at 31 Newnham Road. Is this satisfactory?

U: Is this location in a safe and accessible neighborhood?
S: The India House has a convenient location that is located downtown. I am not sure how safe it is, though.
