I second tinydancer09, we popped out of IoA and enjoyed a wonderful dinner at Cowfish! The food was great (and eclectic), the service was wonderful, and the ambiance fun! I had the BBQ pulled pork "sushi" and loved it! My wife had a burgushi bento box and very much enjoyed it. And our daughter had the bento box with the PB&J "sushi" roll...she thought it was awesome! We actually gave it serious consideration for the next evening for dinner as well, but the heat and our daughter's headache dictated that we left early. We ended up finding our way to Disney Springs and had an AMAZING dinner at Frontera Cocina (highly recommended).
We dined at Mythos for lunch that same day. It was good, quite good. Better than most theme park cuisine, plus the ambiance cannot be beat!
