The downside of course is that it would more than likely bias people's attention towards negative reviews / low ratings. The low-tech solution could be to simply print the good ratings ("4/5 from customers since 2009", "Most liked on FB", etc...), but even that might still cause a few people to question the things that get no comment. That being said, I think it would be an excellent idea for restaurants with quick menu turnover, with seasonal dishes or a kitchen that likes to experiment.
