I'd recommend going in while they have their daily specials. (Have different ones for different days)
If you remember the GameWorks that was on the strip, this place won't be as spacious and more condensed. Still offers tickets/prizes. Wish they had more games they had in their previous location :( choices pretty much were racing or shooting + the sport arcades.
Keep you gamecard so with the next visit, you can reload the card and not pay for an extra.
If you plan on spending some time at the bar, plenty of TV's!! The food is rather pricey, so I'd recommend waiting till happy hour (starts 9pm)
You honestly can't expect any service if you're at the bar just keep that in mind. You might see someone right when you order, then they disappear.
