Are there any restaurants serving middle eastern food?
I'm sorry, there aren't any middle eastern restaurants. Is there another type of food you'd like to try? 
Can you try the search again looking for Portugeuese food instead?
Sure! I actually have two restaurants listed in both the southern and center points of town that serve Portuguese food. Are you interested in one of these?
I would like the one that is in the centre of town. Can you book me a table there for Thursday at 11:30? There will be 6 of us.
I'm sorry, but the restaurant isn't available for that time. Is there another time or day you'd like to try? 
Can you try 10:30 instead?
You're all set. I have book a table for 6 at 10:30. Reference # 2801GMOP. Can I help with anything else?
No, that's all I need. Thank you!
You're welcome. Enjoy your day.
