If I wanted a glass of Hofbrau beer (which I wouldn't, unless I were in Munich at the beer hall) I'd grab a bottle from Total Wine. Not that much difference between German beers on draft vs. bottled, imo.
If I wanted something rare-ish in Baltimore which I couldn't find in a store and didn't want to travel 3000 miles for, I'd go to Max's.
I agree with you about Max's being a dump. But it is a beer lovers dream.
