U: Please find me a place to dine that serves vegetarian food that's in the expensive price range.

S: Oh dear. I did a search for a cheap vegetarian restaurant and my computer doesn't list one. Would you like me to check the moderate range?

U: I am actually wanting the restaurant to be expensive and in the centre of town.

S: I am sorry but there are no restaurants matching that criteria. Would you like to try another price range or part of town?

U: Are there any expensive french restaurants in the centre?

S: Yes, one of my favorites.  Cote on Bridge Street City Centre.

U: Do they have a welcoming vibe?
S: Yes, it's got a relaxing and inviting atmosphere. Can I answer anything else for you or shall I book you a table?
