Some restaurants are really good at it, even chains. If we go to Zizzi, which my youngest especially likes, then you get given a table marker, and all orders from that table are checked by the duty manager, who then makes sure the kitchen staff are aware of the dietary requirements and use a preparation area that's reserved for orders for customers with allergens. So it's possible to do it well.
That's impressive. And a lot of responsibility - I wonder if a duty manager at a chain restaurant is paid a sufficient amount for ensuring someone doesn't die.
