A bit late for a EuroClojure 2014 post but I suppose “better late than never” applies here.
The best part of every conference is the networking. Meeting new and interesting people is priceless and I did plenty of that - mostly over Polish beer and food. Polish beer isn’t the greatest but if you must have it, better stick to Żywiec. It’s widely available and was the one which didn’t give me a headache :) - I’ve been told there are amazing microbreweries though I didn’t get a chance to try any while in Krákow.
