Eating and drinking on set is notoriously difficult to pull off. You see one take, but the crew has done about 17 takes of the same scene. Even with chefs on hand, they can’t bloat the actors up with food. Hence why in most dinner scenes, there’s a lot of cutting and mocked chewing but little goes in their mouth.

It is not that difficult as other directors do it well. I see that in Japanese shows. It is OK if actors pretend to eat or drink when it is believable. In many episodes of Seinfeld we see the actors drinking coffee but we can clearly see that they weren't taking a sip.
