More prix fixe adventures

I guess this is the recession special or the usual way to get diners in during the weekdays, but after musing about the $23 prix fixe weekday dinners at Acacia, I found an identical deal at a recent dinner at Six Burner (@ $24 Mon-Thu). I guess I am violating my general principle of not reviewing the restaurant till (at least) a second visit, but I must continue my rant (from below) that menus need some more imagination (let us forego a discussion on cost at this point because valid arguments may be made on both sides).
This was a practically yawn worthy set of offerings at 6B - a rather tasteless potato soup, an awfully generic beet, arugula salad, 2 fish choices - salmon and scallops, 1 steak and 1 chicken option (again no vegetarian options) and alas...the ubiquitous panna cotta for dessert. After dropping close to $90 for a dinner for two (A glass of wine each + t&t), my tastebuds were barely stimulated and my stomach wasnt full either. I did like their bread though.
I will have to probably try the full menu on another visit (certain options did look intriguing), but I am so disappointed by this visit that I wonder if I should in these days of fiscal discipline. I guess I think that these prix fixe meals should be a bit like an "grande amuse bouche" to tempt one to revisit and order off the full menu. My bouche wasnt amuseed.
