There is an actual bar, and then around the bar there are numerous pub tables and also booths. Kids can not sit at the bar, but can at the pub tables and booths. I was there last August at about 11pm with a friend and my two 14 year old boys. We all shared a few appetizers, and my buddy and I had a few beers (Mom was back at the room with DD). It's usually quiet late at night, especially during the week.
In the booth tables I know they used to be able to give you remote controls for playstation and you could play on the tv that was on the wall at the end of your table. Don't know if they have that anymore though.
There is also an arcade connected to the ESPN club.
