I'll be honest, isn't that what Hard Rock and Margaritaville are for the Universal demographic? It's basically all the same food. With Cowfish and the Grill and Brew, I don't think we need another spin on American type food.
In fact, I'm of the opinion we don't need another restaurant in CityWalk, period.
I'm hoping for a big shop/entertainment concept. A Nintendo World shop with Nintendo arcade machines would be cool.
