Hi, Can you find me a couple of Mexican restaurants for dinner?
Yeah of course, what city?
I'm in Austin, Texas.
What kind of atmosphere or price range are you looking for?
Mid range price and something unique, not too fancy, but a sit down place 
I found two places you might like. Rita's is a popular spot known for their table side guacamole and has a band in there on the weekends. You can sit outside on a nice summer day.
That sounds like a fun spot! What is the second place you found?
Carmila's is a tad fancier known for it's drinks and entrees.
Can you book me a reservation at Ritas? I want to try that place out!
Of course. When do you want me to book the reservation for?
Friday night the 13th
There's no open reservations for the 13th. Is there another night?
How about Saturday the 14th? Maybe a 7pm reservation, if possible.
How many guests will be with you?
There's 2 of us.
Any preference on seating?
I want to sit outdoors or near the band, if possible.
Okay, so there's a 5:15pm on Saturday the 14th outdoors.
Is there anything later?
There's a 7:45pm, but it's not outside or near the band.
I'll take the 5:15 then.
Okay, you are all set for Saturday the 14th for 2 guest at Rita's at 5:15 outdoors.
Thanks a ton.
No problem.
