Yes I am looking to find a restaurant that is expensive in the south of town.
There are 5 options. What food type would you like?
What type of cuisine options do I have?
You can choose between Mexican, Italian, Indian, and Chinese.
I would like Mexican, I would need a table for 6 at 16:00 on Monday
I'm sorry, but they have no openings at that time. Care to try a different day or perhaps a different time?
How about 15:00 for 6 people on Monday?
Yes, I've successfully booked your reservation for 15:00. Anything else?
Could I get that reference number?
Yes. The reference number is SEI1ME8K. The Chiquito Restaurant Bar will reserve your table for 15 mins starting at 15:00. Can I help you with anything else? 
Thanks!  That will be all for today.
You're welcome. Have a nice day.
