Take the DART (train) or bus from the city out to Howth if you want to enjoy the best panoramic views of the city and Dublin Bay. There is a guided pathway down to the fishing village of Howth, with some incredible seafood restaurants. A bowl of seafood chowder is delicious after the walk.
The Little Museum of Dublin is one of my favourite tours to do. It's small as the name suggests but is a fantastic tour and all items in the museum were donated by locals to tell the story of the vibrant colourful past of the city. It is located right on St. Stephen's Green.
Dublin is known as one of the Literary Capitals of the World. Step into a slice of literary history and head to Davy Byrne's pub just off Grafton Street for a glass of Burgundy and a gorgonzola sandwich. Leopold Bloom did this in James Joyce's Ulysses, which is re-enacted in the city on 16 June annually on Bloomsday.
If you are out and about in the city and want a coffee, try Butlers. They are an Irish handmade chocolate company who offer the best hot chocolates and coffees. You get a free chocolate of your choice with every coffee.
Dublin has many a pub and cocktail bar, but there are plenty of hidden gems and speakeasy's to enjoy too. One of my favourites is the Blind Pig at the bottom of Grafton Street in a little underground cellar. They do great cocktails and light bites.
Dublin's most romantic table for dinner is at Pearl Brasserie: here you’ll enjoy a secluded table for two with incredible food. You could walk past this restaurant and not know it's there.
