I was there last in 1981. My mother on the other hand was there just last month.
She said that of the 4 huge arcades they used to have in the 80's they now still have 3 open, and that they are usually fairly busy.
Now the question is, what do they have in there? I couldn't tell ya. My mom being my mom, she doesn't know much about games. For all I know they might now be full of "coin pushers" and crap like that. But who knows.
