U: Good morning, I am looking forward to trying some local restaurants when I arrive in Cambridge next week.

S: Wonderful. Is there a type of cuisine that interests you?

U: I would like to try some modern American food.

S: I'm sorry there appear to be no modern American restaurants in the area. Would you like to try something else?

U: Yes, can you check Chinese for me please?

S: There are 17 Chinese places that you may like, do you have further criteria to narrow it down?

U: what's the most expensive one?

S: I have nine in the expensive range. Is there an area you prefer?

U: No. I would like you to pick the best one you know of.

S: In that case, I would recommend the Sesame Restaurant and Bar. Would you like to know more about it?

U: Do they have a nice view there?
S: One person said that the view was pretty good, but another person said it wasn't anything special. So I'm not totally sure.
