The Bessemer is on Leopold Street, and they have a website as well.
This pub is quite big and has plenty of seating area, they also serve food and have 5 real ales on, they mix these quite often but you can find Moonshine on alot.
There is no jukebox or pool table but they do play background music which isnt too loud and you can hear yourself talk, they also have some very friendly staff.
If you are on Facebook then they have a FB page.
The Bessemer is very close to The Museum, which also serves good selection of ales.
