Alt scene places

Hi does anyone have any interesting place to visit? I'm in cork for 2 weeks and I want to see pretty places like vintage shops, pubs, underground concerts (hardcore, punk, emo, screamo or like techno, sperimental...) or cute markets Like, any interesting place :) Even if I'm in cork I want to visit Dublin where there's more places maybe?

And any Irish food or drink that you recommend? I heard there's a seasonal lemonade yum

Thank you >:)
