To be honest the Fureys are not what they were (IMO) and that is not helped by Eddy being bloody minded for years around not bringing in another piper when Finbar left.
Fiona has handed you a little diamond there though with Maddens. Great place upstairs and down. And if you manage to "over enjoy" yourself of an evening there is a great little cafe a few yards from there (name escapes me) that does a great fry up to settle yourself with the morning after. Don't be afraid to check out some of the bars on the Falls Road either.
As far as Dublin goes, I would see what's happenning at the Clifton Court Hotel? Wouldn't stay there, but if you want some real Dublin as opposed to the Disneyfied Temple Bar you could do worse.
