Brogans on Dame Street have one in the downstairs section.
It was only open at weekends, or when upstairs is extremely busy and staff are available. However, last time I was in there it was being done up so not sure if they've reopened (or are going to reopen - might have been done up as a store room etc.) that section.
[Do be careful though, as the power switch is reachable behind the unit people have been known to flick the switch, turn it back on, put their money in and skip their song to the front of the list ]
