I've been there twice at least, once as a 15 year old on holidays , again when I was about 22 , at Christmas time , I was probably there as well when I was about 8 , but I don't remember if I drank beer then ( likely I did though )
It is a real experience , and the atmosphere is nice in there too , food's pretty good ( all Austrian food is really) but yeah , nothing beats having a beer pulled direct from the Oak Barrel into your stein mug by a tonsured monk in his habit . The beer is really like nectar , slides so easilly , it's cooling in summer and warming in winter and there's a near spiritual buzz from it .
I have to go again to taste it instead of relying on memory
