Don't judge a turkey leg by its cover.. I thought it looked vile at first, but later... well, curiosity got the better of me, so I tasted dh's leg (TURKEY, that is!) In no time flat, dd and I had devoured it and dh was back in line for another. Our 2 boys love em too.
But back to original post idea -- what to avoid -- well, personally, I avoid any "ears of corn". Those things are truly gnarly. If I see "corn on cob" listed on menu, I ask for a substitute. It's a yellow, starchy cylinder of yuckness.
I also thought Pinocchio Haus was a HUGE waste of time and buckage. I'd rather go to a sit-down meal or grab from a cart outside -- it was awfully crazy in there, all for some costly dogs and fries.
