I occasionally scan the ratings for the local restaurants. Indian restaurants are usually near the bottom of the ratings, fast food franchise chains are usually near the top.
In my days of fast food chains it was all stainless steel, constant cleaning, and the grill, drink machines and counters spotless after closing, with zero issues of messy coolers and imperfect food rotation, with mopped floors and all sinks cleaned and shiny.

That and I have occasionally looked up restaurants using the county health department complaints web page.
That gives a totally unbiased look at the establishment along with every violation that’s ever been issued.
I’ve also occasionally submitted a few complaints.
