I took my boyfriend here on his birthday and long story short - we somehow managed to join a group with a free tour. Early warning: don't ever bank on this happening, we were just about to be turned away because tours were sold out and they don't take reservations on the weekends! (A birthday planner's nightmare!)
Anyway, I could describe everything in every little tipsy detail...but the 5 star rating speaks for itself. Go, you won't be disappointed. They'll take care of you and make sure you have a good time. You can tell the employees are happy here.
Make sure you ask to try the unfiltered pilsner and if Noah's there, try to get a tour with him (though I'm sure everyone there is amazing).
PS. FREE BEER
