Sinn Féin's Mary Lou McDonald has said some TDs should carefully consider their drinking.
The Dáil bar has been under scrutiny since the late-night debates on the abortion bill, which saw some TDs drinking into the early hours before voting.
Deputy McDonald told Ray D'Arcy on Today FM that having a bar in Leinster House is a nice facility for visitors, but that TDs should tread carefully when it comes to visiting it themselves.
"It's more than just disrespectful. We have to be clear that when we're at work, the same standards apply to me, as apply to you if you're working in a retail store," she said.
"We shouldn't be any different."
She said that people should feel free to have a drink, but "you don't do it at work."
