I sort ratings by worst but look at the reason. If the 1 stars are "the waitress was rude", then that's fine. I'm there to eat. I don't need them to flatter me. If the 1 stars are "the food smelled foul and I saw them mixing leftover soup back into the pot", I know to avoid it. I've seen both of these types a lot.
And I also do a quick sort by newest. If all the newest reviews are tourists, I know to steer clear. Tourists will give a convenience store egg sandwich 6 stars out of five. They'll write a full-on essay about the fine experience they had at a restaurant and saying it's obvious the chef put lots of care into the meal, not realizing it's a local chain restaurant that just pops things in the microwave. Then they'll take off 2 stars at a good place because the chef couldn't make them a gluten-free, rice-free, beef-free, soybean-free chicken burger (also, they have deadly poultry allergies so they can only eat chicken substitutes). I also see loads of these types of reviews.
I've seen this too, a lot of 1-star reviews from customers who wanted some substitution and didn't get it. Seems designed to be abused by unreasonable customers, cause one of those equates to ~3 honest customers saying "meh" with a 3-star review. I'd prefer the restaurant that doesn't have to charge extra to absorb the costs of avoiding that.
