Hey John (assistant), can you please help me choose a restaurant and then make a reservation?
Sure boss, what type of food are you looking for. 
I am wanting taco's. Any recommendations?
There is Las Margrita's, El Taco, and Chipotle.

I am busy tonight, but thanks boss.
The party will be 4 then. Let me know if you change your mind.
