If you like anything to do with science, you'll LOVE Dublin's Science Gallery. Not only is admission free, but it is jam-packed with interesting facts, things to do and a cafe with some excellent coffee!The exhibits really made me think about the technology and how it affects my everyday life.And if you have a science geek at home that couldn't join you, make a stop at the gift shop. They have some unique gifts that any true nerd will appreciate.
