Please help yourself.

（どうぞ召し上がれ。）
　お茶をすすめるような時の表現のバリエーションについて色々あたってみた。

• help yourself (to something) ＝「ご自由にどうぞ（召し上がれ）」は別に目新しい表現じゃなくて、実際耳にしたこともあったけれど、パーティーとか大皿料理とかで「自由にとって食べてね」というシチュエーションでしか使わないのかと勘違いしていた。ふつうにお茶や食事を「遠慮しないでどうぞ」とすすめる時にも使えるのね。to の後に実際にすすめる食べ物が入ってくると、よりイメージが「パーティー・取り分け」オンリーから離れるかな。（to take some of what you want, without asking permission - used especially when offering food to someone／Please take what you want without asking permission.／to take something freely; to serve oneself without restraint.／to serve or provide oneself with.）
