Some signs of a bad restaurant are too obvious to ignore. Dirty tables, off-putting smells, and inattentive waitstaff are all red flags. However, a strong smell could be harmless if its coming from region-specific ingredients like durian or .

Also, some cultures prefer hands-off waitstaff, so not easily being noticed could mean next to nothing as far as food quality. And while you should never eat at a restaurant that makes you feel unsafe or unwelcome, sometimes the best food comes from surprising places. Looking for life-changing barbecue? Skip the slick restaurants; you'll have better luck with a shack on the side of the road.
