Other mistake: During the dinner Slowik reveals that his restaurant does not have nor serve bread of any kind. Towards the end of the movie Margot requests that he make her a cheeseburger, which he does. Where did the buns come from?
Suggested correction: This mistake completely misses the point. The chef NEVER says they don't have or serve bread; merely that the guests will not be getting bread as part of his meal plan. The movie actually makes a point of repeatedly mentioning the fact that the restaurant is known for its high-quality bread and even shows us a plate of their bread for a few seconds. They have bread... chef is just messing with the customers by refusing to give them any with a pretentious justification.
Suggested correction: He didn't say they didn't have bread. He stated THEY wouldn't get bread for that evening, since it's a common man's staple, and they are not the common man. So, they get a breadless bread plate with nothing but dipping sauces.
Continuity mistake: During the fourth course, after the gunshot happens, all the blood on the floor and kitchen bench disappears when the plates are about to be served. (00:42:12)
Suggested correction: This is simply because they very quickly and effectively clean the kitchen bench off-camera. That is why the man was standing on a sheet and they covered the open kitchen with a screen to catch the blood spatter. The blood on the counter was minimal and there was hardly any blood on the floor.
There isn't enough time for them to have cleaned it. All the blood is clean literally seconds later, and you can see in the background that nobody is cleaning. It's a legitimate mistake. Some of the blood on the bench (and counter) just disappears.
