U: I want to find a restaurant in the centre part of town and serves persian food.

S: There are no restaurants serving Persian food in the Centre part of town.

U: I would like a thai restaurant then.

S: I see several options for Thai food in the city centre. Would you like to narrow them down by price?

U: Yes please. Like to hear least to most expensive first.

S: bangkok city is the only result and it is expensive.

U: If it offers really lovely scenery, I'm interested. Can you get that info?
S: Yes, I can. Bangkok City gets some mixed reviews on their views with some saying it has a nice view while others were not pleased with theirs. Would you like me to find a place with better ratings on the view?
