The Brazen Head is a fun pub. It claims to be the oldest in Ireland. It's about a 20 min walk from Temple Bar. The guided bus tour of Dublin is fun too. It takes about an hour. You can find out where everything so you can take your time later. If you want to break up your trip, Galway is about a 3 hour train ride.

Here's some photos that might give you some ideas
