I've never had it from the tap lol, so I couldn't compare. All in all, I really enjoyed Kilkenny. Very drinkable indeed. Watery yes, but i'm ok with that. Silky smooth head that persists. Went down great. I also like the mild to low carbonation (very few burps..) I will keep buying it. ~$11 for 4 cans.
I've read that cans still beat bottles as the light penetrating the glass does some things to the beer....
