Jumping off the topic of Pizza, it has been my experience that Trip Advisor Reviews are NOT reliable at all, not only for scuba diving posts, but other reviews as well. The review system used by TA is subject to being gamed. Let me give an example. I travel quite often (2-3 times a year) to Cozumel. And I am definitely a Foodie -- I'm always on the lookout for new great restaurants. About 4 years ago, I was going to Cozumel, and it was recommended by someone that I trust that I try out a new restaurant in Cozumel, Danube. I ate there, and the meal was outstanding in every way. The food was done perfectly, the service was great, the view out over the Ocean was fantastic. It was just an excellent experience. So I posted a rave review on TA. At the time, there were a number of other rave reviews, including at least 6 from friends of mine (none of whom were from Cozumel or had any interest in the restaurant). Danube had very quickly moved up to #1 on TA's list of recommended restaurants for Cozumel. But less than a week later, my review, along with every other positive review of Danube, has disappeared from TA. It seems an anonymous tipster had claimed to TA that Danube was paying customers for great reviews (not true) and was posting its own reviews under fake names (again, not true, at least so far as I know). TA never attempted to verify this tip, it just deleted EVERY positive review of Danube, and demoted Danube to the very bottom of its list of Cozumel Restaurants. Danube was shut down for lack of business within 4 months. If it is that easy for a competitor to kill a restaurant on Trip Advisor, I just don't think its ratings should be trusted at all.
