Hi! I need to find a cheap restaurant in the centre.
There are 15 restaurants in the centre that serve cheap food. What type of food do you want?
No preference. Please recommend any one of those restaurants.
How about dojo noodle bar. It is on the cheap side and located in the centre.
Sure, can you try and book a table for Wednesday at 12:15?  There are 5 people.
I'm sorry but there are no available tables at that time, would you like to find another restaurant?
Yes, what other restaurants are in the same area in price range?
There are 15 such restaurants. How about the J Restaurant? It also serves asian oriental food. Would that work?
Any place I can get in to will be fine, in that are. 
Okay I will make reservation for J restaurant is available.
