U: I'm looking for an inexpensive restaurant in the west section of Cambridge.

S: I have an Italian place and a Vietnamese, which would you prefer?

U: I would actually prefer some cheap Lebanese food if possible?

S: I am sorry I have no results for restaurants serving lebanese food in the west.  Would you like to find another type of cuisine?

U: Ok, maybe we can try the Vietnamese one you mentioned.

S: Okay would you like me to make a reservation?

U: Um, I think I'll just take the postcode and the name for now thanks.

S: The Vietnamese restaurant is called Thanh Binh and is located in the CB30AF postcode. Is there anything else I can do for you?

U: Do the reviews mention anything about a welcoming vibe?
S: No, the reviews by previous patrons of the Thanh Binh mention a rather mediocre and lame atmosphere at the establishment.
