Well, another advantage of ...Qf6 is that if White takes, the recapture places Black's king's knight on a better square. On the other hand, if White doesn't take, with ...Qe7 the f6 square is still free for the knight.
The question really is, if everything had gone according to book, where would White have been? Black would have had two pieces dev ...[text shortened]... f that is the way this opening is supposed to go, personally I'd pick a different opening.
I play the Lowenthal as Black, although I very rarely seem to get the Open Sicilian played against me. The main line is indeed 7.... Qf6. There are four main moves for White here: 8. Qd1, 8. Qa3, 8. Qd2, and 8. Qc7. Qc7 and Qa3 are a little more aggressive.
While Black does have a little activity at this point, it is difficult for him to arrange to play ....d5 without sacrificing the pawn. He needs to play actively and aggressively to avoid White getting a positional stranglehold. Plans include b5-b4, Nd4, and in some cases d6 and f5 instead of d5. White's setup often includes Nc3, h4, Bg5, o-o-o, and Bc4.
You shouldn't be afraid of the Lowenthal as White - play good positional moves and you will emerge into the middlegame with a solid game.
