A better approach is:
Congratulations Jane on that new promotion!
When people smile it brightens up the restaurant, Thank you.
May I offer you another glass of wine?
The spices in the meat were just right tonight, what do you think?
The chef is proud of the Butternut Squash Ravioli.
The Merlot is perfect with that pasta.
Accentuate the positive, engage the guest and do not ask Is Everything OK?
