Sorry your experience sucked. Your experience is the exact reason we decided to skip the restaurant on opening night. To many things in there would need to get worked out. Try the Italian Hot Dogs in the Taste of Newark section. They were fab!
Our over experience was good. Trains in and out were easy for us! The Arena Bar was great for a warm up!! The lines didn't seem to be too bad inside.
There are things that can be better, and I am sure they will be. Over all I am pleased, and never ever plan to return to CAA.
