I'm not a local, but wouldn't eat at a restaurant if it was staffed by people from that specific neighborhood documented in the submitted web page. That's regardless of their ethnic background: they could be milk-white Bulgarians.

I would expect them to show up in dirty clothes, and not having bathed in months, and neglect to follow basic hygiene like washing their hands. They would likely perpetrate actions like tasting food and putting the same utensil back into the pot, completely lacking the inhibition of refraining from doing whatever comes naturally.
