The problem is, a single review is more or less worthless. Unless you give a variety of reviews (1 through to 5 stars), you are a pretty useless signal. There's no way they can see if you are a discerning critic who only gives 5 stars if it's the best meal you've had in years, or a Homer Simpson type who'd give 5 stars to Burger King the time they accidentally upsized your fries. Or that the restaurant in question requested people review it if they loved the experience. The disadvantage to this approach is that only the pretentious wankers who review every meal they have get any real pull. Funky places that cater to people with strange tases will lose out, because OMG the garlic was almost RARE!
