I'm as concerned about the cleanliness of the workers.
It depends on location....I can’t attest to what goes on in the kitchen,but the restaurant locally is clean,orderly.
Wherever restaurants hire illegal aliens, just realize that, by entering illegally, they avoided any semblance of a medical vetting, and are now handling your food. Meanwhile measles enjoy a resurgence in Texas, a border state, and TB and smallpox are appearing as well. Happy dining.
