U: Hi.  I was wondering if there are any Eastern European type restaurants in the south part of the city?

S: Unfortunately, there are no eastern European restuarants in the south part of the city. Is there anything else you want?

U: I'm looking for an expensive eastern european place in the south.

S: Unfortunately, I don't happen to have any listing that meets what you were looking for. Would you like me to try either a different area or type of restaurant?

U: How about a Chinese restaurant?

S: Certainly, we have two expensive Chinese restaurants the good luck chinese food takeaway, and peking restaurant. Would you like a reservation at one, if so for how many?

U: Is the Chow Mein fresh at the Peking Restaurant?
S: I can't speak to how fresh it is, but the reviews of the Chow Mein are very positive. Can I answer anything else?
