1. You state that this dish was precisely what you wanted and asked the waiter for. It should not be a surprise..that is what normally happens...but maybe you are excited at going out!
2. Your enthusiasm for the evening overwhelms you...or maybe you are just really hungry! You identify this dish as your own and state that nobody can have it - it is only yours!
All these terms would be good to say that the dish coming out is yours so you would say
"that one's mine" or That one's for me" meaning its your dish and not someone else's on the table
三例とも、出てきた料理が自分のものだと言うときに使えます。
例えば：
That one's mine.
That one's for me.
（それ私のです）
同席している他の人の料理ではなく自分のものであると伝えています。
When at a restaurant, if there is more than one person at the table, when the waiter brings the food to the table they will say the name of the dish with the hopes of giving the appropriate dish to the right customer. When you hear the waiter say the dish that you ordered, you can simply say, "right here".
You can also say, "That's mine" , "That's me" , "That's what I ordered" , "I ordered that", That's for me, thanks".
レストランでテーブルに2人以上の人がいる場合、ウェイターは、料理を持って来た時、それを注文した人にきちんと渡せるように、料理の名前を言います。
ウェイターが自分の注文した料理の名前を言ったら、シンプルに"Right here"（ここです）と返答できます。
その他に、
"That's me"（私のです）
"That's what I ordered"（それは私が頼んだ物です）
"I ordered that"（私がそれを頼みました）
"That's for me, thanks"（それは私のです、ありがとう）
と言うこともできます。
