Once you've ordered a takeaway, look at the photos of the store and prioritize the ones you've been to, and the regular restaurants that are open to the public. If you haven't been there, look at the photos on the platform before ordering a takeaway, and if they all look like they have a worrying hygienic environment, then it's best not to order it.

Also, check out the news after you've chosen one, or use (name of restaurant + penalty) to search for any negative reports.
