Are there any cheap Indian restaurants around?
Yes I have 3 in the center and one located on the north side of town. Do you have a preference?
Yes, I would prefer the centre.
I think Kohinoor, The Gandhi, or Mahal of Cambridge would all suit you. Would you like to book a table at one of them?
Let's go with the first one, Kohinoor. Do they have a table for 2 available at 1pm tomorrow?
For what day please?
Wednesday, like the girl from the Adam's Family. 
Sorry, there are no tables available. Would you like to try another restaurant?
Another place to eat, any type, Centre and cheap. 
I was able to book you at The Gandhi. Your reference number is R9XJC41B. Is there anything else I can help you with today?
Actually, I just found out that another couple will be joining us and we'd like to eat at 17:15. Can you make me a reservation for 4 at that time?
Yes sure. your reference number for the new booking will be 47N2K0RG.
Thank you. Goodbye.
You're welcome. Have a lovely day.
