I'll be in Dunedin in March. I've been there a few times now, and everything seems pretty quiet at night time. Where's a good place to hang out after dinner? Are there any live music venues? Where are all the students?
Make the effort to seek out a fantastic bar tucked away down a back alleyway off Moray Place called "Pequeño". I had a brilliant time there earlier this year and would highly recommend it as an alternative to some of the more commercial, lame spots on the "Octagon".
