Mythos for us was ok, food was ok but service was horrendously slow. Server lost money as tip would have been bigger with a bigger bill if he'd bother to come by and offer more drinks (lunch and not super busy). DD and I enjoyed Finnegans last September - was a good place to hang out and eat while park converted to
HHN. Lombards last fall was really good too-like it much better than Red lobster. Confisco is a hidden gem.
Our favorite though has to be NBC Grille-it is the one place we go to every trip. Enjoyed Toothsome but not enough for a repeat yet. Cowfish was probably our least favorite-burgers alright but yeck for sushi (from my sushi loving son who's turned into a bit of a snob there..)
While we enjoy the Harry Potter restaurants, we have a food truck here called London Calling that is really good British food (from his families recipes), and the food at the restaurants is OK it isn't as good as what we get at home. However they are worth the atmosphere alone!
