Thanks.  I am also looking for a restaurant in the centre that serves African food.
I found Bedouin matching your request.  Would you like to book a table there?
Is it in the moderate price range?
No it is in an expensive price range.
Okay let's look for a moderately priced international restaurant, book me a table anywhere for 8 people at 14:45 on Monday. 
I am sorry but there are no moderate price international restaurant available.  Would you like to try another food or price range?
Okay, then let's go back to my first choice, African cuisine. You mentioned the Bedouin, earlier. Is it in the city centre?
It is located in the centre and is expensive.
Yes, I would like to book please.
I reserved a table for eight people at the Bedouin on Monday at 14:45. Reference number is LGUNVWOU. Hold time will be for 15 minutes. Is there anything else?
Have a nice day.
Thank you. You as well!
