Guiness Storehouse
It is the last place I visited and it left me with a memory of the 306 degree bar views of the city while trying a pint of Guinness (or a soda if you don´t drink alcohol). The museum was very good, fun and didactic. Don´t forget to pick up the audioguide in Spanish in the entrance hall. The store on the bottom floor has good prices and you have to buy some Guinness things, and it´s one of the best places to do it. I´ll leave you the video.
