The inspection score itself is just one data point, and yeah, it can be gamed. What people don't always realize is that you can usually dig into the actual violation details online - most health departments post them publicly. That's where you get real intel. A violation for "missing date labels on food" is totally different from "evidence of rodent activity," and knowing the difference changes how much you should worry.
Beyond the official paperwork, trust your senses when you visit. Walk past the front counter and look at the general cleanliness - are the menus sticky, is the floor gross, do staff look like they actually wash their hands between tasks? You can also check online reviews and see if people mention specific concerns about food safety or cleanliness. The combination of a recent decent inspection score plus your own observation plus what other customers are saying gives you way more confidence than any single score ever could.
One thing that actually helps: ask the staff casual questions if you get a chance. Restaurants that take cleanliness seriously usually have staff who can talk about it without getting defensive. If someone seems annoyed when you ask about their food handling practices, that's a yellow flag. Places that are genuinely clean tend to be proud of it.
