Saturday night at Shamrock Irons, 9pm start. The pub's got that lived-in feel where you can actually hear whoever's playing, and weekend crowds there tend to settle in rather than pass through. You can post up close to the stage if you want to be in it or grab a table toward the back with a Guinness and shepherd's pie, the setup works either way. Most nights feature live music with no cover, so if you dig catching acts without committing your wallet, this College Street spot delivers.
