Maria's Packaged Goods & Community Bar

I've never been to Maria's before, but I'm going to this.

From the info on their website, it sounds like there are sort of two events going on at once. One at the bar where everything is a la carte, and another at their art gallery, with a $15 cover, but all you can drink.

Are the beer lists the same? Different?

Does anybody have a suggestion of where it is best for me to go? I assume the overall selection will be better at Maria's, but I could be wrong!
