I need help finding a portuguese restaurant located in the centre, can you assist me please?
Hi I found a restaurant. It is Nandos city centre and it is located at 33-34 Saint Andrews Street. Would you like for me to book it for you?
Is this restaurant in the cheap price range?
Yes, it is. May I help you book?
Yes, please book for Thursday at 12:45 for 7 people.
Booking was unsuccessful. Would you like to try another restaurant?
Hmm, okay, how about another restaurant in the same area and price range?
There are several. The Gardenia served mediterranean. You might be interested in it. Ask and Zizzi serve Italian.
Okay let's try that place.
Great news I was able to book you into there and the reference number is 2HILQZBF .
Which restaurant were you able to book me into?
I was able to get you in at Ask on Thursday at 12:45 for 7 people. There is a new reference number, though. Use 0SLQNHXA .
Thank you. That is all I need.
My pleasure! Have a nice day.
Thanks, I'm all done here.
Thank you and I hope you enjoy the restaurant. Have a great day.
