Task-oriented dialogue about: restaurant

I'm looking for a place to dine that serves Vietnamese food in the East.
Sorry, there are no Vietnamese places in the East. Would you like to try a different area?
Yes, I am willing to go to a different area for Vietnamese food.
Thanh binh is in the west part of town
How about an international restaurant instead on the east?
The Missing Sock is a cheap restaurant on the east side of town that serves international food. Would you like more information on that place?
Yes please. Can I get the postcode.
Sure, the phone number is 01223812660.
Not the phone number, the postcode, please.
My apologies. The postcode is cb259aq.
Thank you very much. I am all set. Bye.
You are welcome. Good bye.
