Are these sentences OK? Or how would you say it?
(at the dinner table, some food in a plate)

If I ask;

Did everyone get this? or Did everyone get of this?

Question

Are these sentences OK? Or how would you say it?
(at the dinner table, some food in a plate)

If I ask;

Did everyone get this?  or Did everyone get of this?

Answer

If we are talking about food, you can say

Did everyone try this?

Answer

If you are providing food for diners, "did everyone get this" may be more appropriate. 
example

You are serving something and want to make sure everyone has been given some, "did everyone get this"  or ' did everyone get some pasta /salad/potatoes/etc.' would be acceptable.

If you are dining, and are looking to ask if anyone has tried a particular dish, then both previous answers given would be suitable.

Best of luck

Answer

"Has anyone tried this?" would be the best way to say it, or if you want to know if they have tried it other times maybe use "has anyone ever tried this?"
