Need a train leaving on Thursday after 14:30 I found 195 trains that match your prerequisites. What is your destination? I am going to London Liverpool Street from Cambridge. Train TR3237 arrives at 17:27 and cost 16.60 pounds. Would you like me to book it? No thanks, I'm not sure how many seats I'll be needing yet. Okay. Just call us back when you do. Oh, I am also looking for an African restaurant in the centre...North African, to be exact. There aren't any in that particular area, do you have any alternative preferences? Hmm, can you see if there might be an expensive restaurant that serves specifically "north african" food in the centre of town? I apologize, but we are don't have any North African restaurants in this town at all. I do have an expensive African restaurant in the centre. Will that suffice? No, if I can't get North African I'd really prefer something radically different. Chinese, maybe? How about the Ugly Duckling? They serve chinese food and are located in the centre of the city. Okay. can you book me a table for 7 at 11:00 for Thursday? That booking was unsuccessful. Would you like to try another time? Sure, can we try for 10:00 instead? Booking for 10:00 was successful. Your reference number is XVUUCPBH . Is there anything else I can help with?
