I need a place to stay, ideally it should be 3 stars and moderately priced.
Sure, there are some nice guesthouses to choose from.  Would you like to stay in the north, south, or west of town?
Centre, please! Thanks!
Unfortunately there aren't any hotels available in the area that are moderately priced.  Would you like me to look in a different area?
Ok that's fine, let's try something in the west then please, I really need a room
There is Hobsons House located in the West that meets your needs. Would you like to book a room now?
Yes. That sounds good. Can you book it for 1 person and 2 nights starting from monday?
It is not open then, maybe a shorter stay?
Okay, try just 1 night instead.
I booked your room for 1 night.  Your reference number is IR6YZXFD.  Can I help with anything else today?
I am also looking for a restaurant, maybe with english food?
There is no restaurant serving english food. Anything else?
Could you try again, English food, moderate priced in the centre of town. 
I'm sorry, but there are no restaurants serving English food in the city. Would you like to try another cuisine? Maybe British?
Yes, can you list some that serve Indian food?
There are 22 Indian restaurants do you have a price range and area you prefer?
I'd like it in the same price range and area as the hotel, please.
There is the Meghna restaurant that fits your criteria.
I'll take that for 12:30 on monday for 1 person.
Your reservation was successful. The table will be reserved for 15 minutes.
Reference number is : L5A3CSWF. Is there anything else I can help you with?
Nope! That should do it, thanks!
Thank you, let us know if you need any more help. Good bye.
