I am looking for a cheap restaurant in the south part of town.
How about nandos, a portuguese place ?
Is there anything else available? 
The Lucky Star is also a cheap restaurant in the south part of town.  It serves Chinese food.
OK. Can you give me the address of the Lucky Star?
The Lucky Star is located at Cambridge Leisure Park Clifton Way Cherry Hinton. Is there anything else I can help you with today?
No that would be all. Thank you and good bye.
Thank you for using the Cambridge restaurant system. Goodbye.
