Best Brewery in Bozeman to Stop at for the Montana Brewery Passport Stamp? [Poll]

I love beer just as much as I love going to concerts.  Headed to Bozeman this weekend for the Kiss concert.  Would like to get a stamp in my Montana Brewery Passport.  Which brewery would you hit?

I love IPA's, so let focus on the one with the best IPA or maybe the one that has the best burger.  I'm sure all of them are good but some must better than others.  Only in Bozeman for two days.  Want to make sure I consume the best beer in my limited time there.  Rock concerts and beer, that's how I'll spend my vacation.
