Here you go, all I had was iced tea so I hope that's ok.
お待たせ は英語で Sorry for the wait, sorry it took me so long, thank you for waiting, sorry to have kept you waiting 等です。家に来てくれた場合はSorry for the wait や sorry it took me so longが一番ベストかもしれません。時間があまり経過してない時は上記を使うと不自然になる可能性があります。その時は Here you go を使うといいと思います。
