Hi Dasha In theory, people would be correct. In practice? We usually just ring a restaurant (or walk in the door) and request 'a table for two please.' It is understood that the two concerned are people rather than cats or umbrellas..

The use of the plural 'persons' is only for formal contexts. You might see it in legal contracts and official notices, for example. We never use it in everyday or spoken English. So, for example, you might see a sign in an elevator (lift) which says 'Maximum capacity 8 persons'. But you would never say this : in speech, and in ordinary written language, you'd say something like, "You're not supposed to have more than eight people in here." And getting back to your original question, if you're asking for a table in a restaurant, you'd say that you want a table for two people. Or, as Andrew says, simply a 'table for two.'

Both are correct grammatically but as Andrew said, "table for two" is the way for the reason given by him.

I think both are correct !

Table for two people sounds most correct to me.
