Task-oriented dialogue about: restaurant

I am looking for a place to dine. The restaurant should be in the east and should serve swiss food
I don't have any restaurants that meet that criteria. Are you interested in something different?
No, I am only interested in a restaurant that serves swiss food and is in the east.
I am sorry but there are no restaurants in the east that serve Swiss food.
How about international food?
The missing sock will meet your needs. Need to book a reservation?
No, I just need the postcode.
The post code is cb259aq. Is there anything else I can help you with?
No, you have been very helpful. Thank you so much.
Thank you goodbye
