user
i am sorry , i could not find any portuguese restaurant -s in the east . shall we look in a different part of the city instead ?
assistant
are there any that are in the expensive price range ?
user
i am sorry . there are no expensive portuguese restaurant -s in the city . there is , however , a cheap portuguese restaurant in the south and another in the centre . do either of those interest you ?
assistant

user

assistant
