Molly Malone's on Hope Street, just between Sauchiehall Street and Renfrew Street is a rather large Irish pub that servers excellent lagers and stouts from tap as well as all kinds of strange drinks and food too.
They've got live music at 9.30 PM every day of the week and it can be of many differents kinds. On the saturday we were there there was a band playing U2 and stuff, but the volume was so loud we (and many others) had to leave. But on the other hand we went there on the sunday evening too and then there was 5 irish guys playing traditional irish music on guitar, irish drums etc. They played really well and it was a nice evening out, talking to my friends.
