Como dizer "Esta refeição dá para quantas pessoas?" em inglês

Uma opção: "How many people does this dish serve?"... Refeição (dish, meal, plate, portion...)

I am not a hundred sure, but my educated guess is "is it (the dish) enough to feed 2 people? Or n some cases: "is the portion enough for two people?".
In America is said that restaurants pack their plates with portions 2 or 3 times the recommended serving size, so you know that you can share a "Heart Attack" sandwich without having to ask that. Oh, no, if don't eat it all ("the Heart Attack, I mean), the staff will spank you with a paddle! Ha ha ha, those kidding folks!
