It's difficult if not impossible to get real ale in Spain.
The casks must be kept ideally at between 10 and 13 degrees Celsius. There are no bars that I know of in GA with a cold cellar such as you find in the UK. As 'Blue and white stripes' has mentioned, Dick Turpin's is the place to get bottles of British beer.
Lager is pretty tasteless to me so I usually bring a stock of bottled beer in the car when we drive down.
