The Cobblestone is on the north end of Smithfield square, and Smithfield square is on the north side of the Liffey. Any tourist map will show it. The Cobblestone has a great session on Wednesday night -- and this is a REAL session, not one of those put on for tourists. When I was there, there were 9 musicians, standing room only, and not enough of that.

If the Cobblestone is too crowded, try Chief O'Neil's for a while. It's in the refurbished old Jamieson distillery, which also faces Smithfield square. The atmosphere is like a shopping mall, but the music is good and it's not likely to be crowded.
