Thanks for all the info. I understand your point about a sports bar during oktoberfest. My personal concern is my lack of German coupled with my lack of knowledge of Catholic services and traditions. I just don't want to be "that guy", who is totally lost and confused.
However, on your advise, I'll push on and attend. I assume dress is formal - suit or the like?
If anybody is going to be in town and also wants to attend with me or even sit down to a maß on Saturday. Post here or PM me.
