I spent a lot of time at Gameworks in Vegas as a kid and it was a pretty awesome arcade with 100s of games and a sweet deal for unlimited play by the hour. I think it was $10/hr, but were talking almost 20 years ago now...
A buddy of mine who still lives there told me a a while back that the original Gameworks closed, but i just looked it up and its now at town square still on las vegas boulevard, but at the 215 instead of downtown. It never made sense to me as a kid to have to walk past drunken debauchery to get to a freaking arcade, but at least its moved since.
Also i live an hour from Santa Cruz now and i dont recall at least on my last visit the arcade being anything special. Theres a couple old rather crappy games available, but if I were to do anything in that "arcade" it would be minigolf. Youll see it if you stop by and dont forget to ride the roller coaster!
