I'm looking for a place to dine that serves expensive european food.
There are five restaurants that meet your criteria. 3 are in the center of town, 1 is in the north, and 1 is in the west. Do you have a preference?
Any of those should be fine. Can you see if you can get me a table for 2 at 14:45 on Saturday?
Booking was unsuccessful for all restaurants. Would you like to try for another day or time slot?
I would like for you to find me one on Saturday after 12:00. Can you please book me for one with that time in mind?
This time slot was also not available.  Was there another day or time I could try to book for your restaurant visit?
Are there any times which are available on Saturday?
I'm sorry, but I'm experiencing some system errors. Can you please restate your preferred time for your reservation?
I would like a reservation at an expensive european restaurant anywhere in town at 13:45 on Saturday. Can I please have a reference number? 
Thank you for restating your requirements clearly. Your table is reserved, and your reference number is DMIEPETY. Can I help with anything else today?
