I find this app very useful. Ive used in various parts of the world to spot a good dish. Though I do double check the rating of the restaurant at tripadvisor if I am in a foreign city.
I do not like that people post food made at home but that is easy to hide.
Also I think I am missing a "bad food" or "bad place" button. Could be very helpful.
Overall I love it.
