The whole block that Cheers was in (called The Cafe Royal) was closed to make way for a new 6 star hotel called The Cafe Royal Hotel opening end of 2011. Many bars and clubs within that same block closed on the same night as Cheers (31 Dec 2008) including Chinawhite, Paper, Dolce and of course the famous Cafe Royal itself.
There is a bar named Cheers in Boston, but that's not where they filmed the show. The exterior shots are authentic and you do walk down from the sidewalk to enter. In another part of Boston (the Market), they have a bar called Cheers where the bar is a replica of the bar in the show. But it's above ground with plastic sheeting for walls.
