Looking for some advice! Newbie to business school process

Sorry for the length...

I graduated in 2010 from Northeastern University with a BS in architecture. Post-graduation I chose to take time off from school and get some work experience before going back and getting my MARCH, partially due to emotional burnout and frustration with a field. I've since decided that I would like to forgo the advanced architecture degree and pursue an MBA.

I have a few goals in obtaining an MBA, thought they're not exactly related. The first, most immediate goal is to open and run a microbrewery with my boyfriend and our family. It's something I've been extremely passionate about the last two years - homebrewing, reading books on craft beer and brewing, volunteering at many local, large scale craft beer conventions and helping out with local nanobreweries and general becoming familiar with the local players on the vibrant craft beer scene in Boston. So why not just start a brewery? While I know beer, I'd like to have some ability to know what I'm doing in running a business in order to be successful. I'm excited about using my time in business school to help develop the business plan and expose myself to different kinds of entrepeneurship to maximize my education and experience.

I also like the idea of having a degree other than architecture as a safety net. Going to work for an aid organization with an MBA and a background in architecture is an attractive option that I don't mind having as a backup plan. I guess I feel kind of weird coming from an architecture background and saying I want to open a brewery when (in my mind) so many people apply to business school to work in finance or or change the world in some way.

My undergrad GPA was 3.295. I am taking the GRE next month and feel very confident about my ability to do well on the test (since the decision to do business school was recent I was already well into preparing for the GRE so I' am sticking with that instead of doing the GMAT). I have 2 years of post grad experience as a project manager in a small general contracting firm, plus 3 6-month co-op work experience in architecture firms while in my undergrad.

I'm planning to apply to Babson, Boston College Carroll School, and Boston University School of Management. I'm very familiar with what it takes to get into pretty much any architecture graduate program in the country but have just starting learning what it takes to get into business school. Am I an attractive candidate? Should I emphasize by passion and entrepeneurial ambition to start a brewery or downplay it by highlighting how I could use the MBA to complement my architecture background to find a way to work within and alter a field which I've become disillusioned with?

Thanks in advance, I'd appreciate any feedback!
