Download the file from here:
https://drive.google.com/uc?export=download&id=1NeFwbrgVSroMIR5OUVG0ki_v79ALcsHh
Go to your server /public_html/app/Controllers directory and upload the downloaded file.
(there is already a file with the same name, so make sure you replace the old one with this new one)
NOTE: take a backup of the file on your server first (only RestaurantController.php)
Then check the same restaurant "Aryans Bakery (Ponkunnam)" where you were having issues.
This time it should say that the restaurant is not operational.
Let me know the results.
