IMO, its a shame that Hot Dog Hall of Fame never caught on more; it was a solid spot that just had a rough location and was a little higher on prices than ideal.
That said, I feel like whatever replaces this space really should not be a Table Service restaurant; CityWalk is a little bloated with TS options, and all of its QS options are in very unideal locations. A high quality quick serve where the current USS is would do gangbusters.
