While traveling through Granada this summer and searching for a site with air conditioning to escape the 45 degree heat, I found Hannigan and Sons Irish Pub. It's a classic Irish pub, has free WiFi, sport, etc. A good mix of giris (foreigners) and local Spanish people. Calm during the day (laptop time) and lively after 10PMish, I found it was a good place to meet people while traveling and while enjoying a pint of Guinness.
In between Calle Elivra and Gran Via, a few blocks down from Plaza Nueva.
And they have a website:
