Google's Maps search ranking doesn't seem sophisticated to me. In fact it seems unbelievably naive. Ranking is Google's core business and yet they seem to forget how to do it when a map is involved.
When I want to find something that's actually good, I use this site: https://top-rated.online. At first glance it looks like an unremarkable SEO spam site, but it's actually a great way to get properly ranked Google Maps reviews. It uses proper Bayesian ranking, so it won't show you a 5 star place with two reviews over a 4.9 star place with 2,000 reviews, as Google often will. And it has good sorting and filtering options so you can, for example, filter or sort by number of reviews.
