Yes it is. I was last there a couple years ago, but it was $15 to enter (recently upped to $20) then play all you want all day. I think a few had credit buttons, but most were on freeplay if I remember correctly.
I was at Gameworks a week or so ago and they were definitely credit-based though. Of course that meant swiping a card rather than inserting coins, but credits just the same. The few classics were just one credit, up to I think 12 credits for a Star Wars game with a pod you sat down in. There was a theater/ride-type game for 20 credits, but that was something special where you strapped yourself in, had fans blowing in your face for wind effects, and you just shot at zombies (other enemies in other chooseable scenarios) in a rail shooter for a set time until game over.
