It's a large arcade around the back of the Gaumont Cinema, simulators, games, air hockey, pool and bowling.
The leaflet I have doesn't give any of the charges but everyhting is token operated, if you see anyone handing out leaflets, get one there are some vouchers in the back for free plays, extra plays, etc.
Bet you won't have time
I'd promised we'd visit the arcade and go to the Cinema too on our last visit, but there's just not enough hours in the day when we're at DLRP.
