お弁当

昨日、父と日本料理のレストランに行きました。私はあひるのお弁当を食べました。父もお弁当を食べましたが、彼は鮭のお弁当を食べました。おいしかったいですした！＾＿＾

(Did your lunch have cooked duck meat, with the form of duck or duck drawing on the lunch box? Did his have grilled salmon? In my opinion, it can be understood as several meanings and I'd like to know more details.) 

Good job! I hope this helps you.
