頂きます！

I'm often asked how to say 「頂きます」 in English, and the truth is we don't have any such expression. Some pious Christians say grace but generally there is no expression before eating (or drinking).

Furthermore, there is no equivalent expression for 「御馳走様でした」 in English. The best way is to say thank you and praise the cook, chef or host.

For example: Thank you, that was a lovely meal! or Thank you, you're a great cook! or What a wonderful meal, thank you so much!
