good luck dude, I was in Spain 15 years ago (not Barcelona)
more bars per capita than any place I've ever seen, all opened early too, and they all had these 6 ft bar tables with pockets that had circular holes like a golf course, brutal, and all run down and shabby and filthy
I managed to find a single carom table in some shabby arcade and a coin op in a mall, think it was an 8 ft valley
a couple places also had uk style 7 footers with the small balls and snooker pockets, reds, yellows and the single black ball
plenty of fooseball though, NEVER play a Spaniard for the cash at that game, lol, I took a few pesatas off a dude shooting pool and he took it back at fooseball beating me 20-19, oh and he gave me a 19 point lead making moves I didn't even think were possible, lol
fast forward 15 years and I've just described the Toronto scene
Barcelona should be a blast right now with the upcoming world cup
