I want to find a cheap restaurant serving hungarian food.
What area would you like to look in?
I do not care about the area as long as it is hungarian food and cheap. 
There are no hungarian restaurants I can direct you to.  Would you like another type of food?
Yes, how about a restaurant that serves modern european food?
The the river bar steakhouse and grill is cheap and serves modern european food
Can I get the address and postcode?

That's it, Thank you, goodbye
You're welcome and goodbye.
