Meh... Goretorium didn't really have that great of a location. I suppose it was great in terms of "middle of the strip", but not great in terms of the fact it was part of a very long, dull, tourist trap/strip mall connector hallway. It wasn't part of a casino, and it was practically surrounded a magnet kisok and a store that sold novelty socks. Not really that appealing of a location. It didn't even really have any close access to a parking lot.
Also, while I seem to recall it had a bar, it was minuscule (maybe 8 stools) and barely themed. The place practically had zero curb appeal.
Now, it's still not a given this place will be successful. But being it's own building, more (I presume) free parking, adjacent to the successful Area 15, and having a much more elaborate full restaurant and bar will definitely put things more in it's favor.
Will that be enough? Still hard to say, but I'm a bit more optimistic. Even if it does ultimately go under, I think it'll hang around for a fair number of years first (Goretorium lasted barely just over a year). If nothing else, it has the backing from Universal, so they'll have some money to throw at it if it flounders (another luxury that Goretorium did not have).
