Answer:
Dine at the restaurant without alerting the management that she is coming in to do a review.
Explanation:
Food journalists are those journalists who 'taste-test food from restaurants and acts as judge or critiques. Such a post is one that helps keep restaurants in competition and also helps maintain the quality of foods served.
The most important point as a food journalist is to maintain anonymity as much as possible. This will ensure that the critic will arrive incognito to the staff and be treated as a 'regular' customer and not treated in a special way. The main point of this visit is to evaluate the restaurant and provide genuine and real feedback on the place. So, a reporter planning to write a review of the newest restaurant should go to the place without any prior information or notice and act normal, as a normal customer and not give out any indication that he/she is doing a review.
Thus, the correct answer is the third option.
