I need to find a cheap restaurant on the North side
There are 2 inexpensive restaurant in that part of town.  An Indian restaurant called Royal Spice and an Italian place called Da Vinci Pizzeria.
Does either have availability for a table for 5 people on wednesday at 18:45?
Yes, there is an available reservation at Royal Spice during that time frame. Do you want a reference number for your reservation?
No thank you that will be all
Okay, thank you.
