Task-oriented dialogue about: restaurant

I am looking for a place to dine. The restaurant should serve mediterranean food and should be in the south
I'm afraid there aren't any. Would you like to try another area or cuisine?
What restaurants are cheap?
Nandos is cheap in that area.
how about one that serves portuguese food?
Nandos serves portuguese food in the south area. Would you like a reservation?
Yes, please. 3 people at 12:15 on Friday.
Booking was unsuccessful. Is there another day or time slot you would be interested in?
how about for 11:15?
Yes, that did the trick! Your reference number is OTN7HHGY and they'll hold the table for 15 minutes. Is there anything else I can help you with?
That is all I need, thank you.
You're very welcome. Good day.
