I've also been to MM in Charlottesville and Asheville.
Charlottesville was heavier on the preppy college kids, with families blended in. Then again, I typically eat at times when families are out eating.
Asheville was heavier on the hemp people (with famliies blended in). But that's all of Asheville, isn't it?
I walked by the MM location in Denver, and it seemed to be filled with mainstream tourists who had no clue that better beer and food lay elsewhere.
From what I remember, the beer selection at Asheville was very good (this was years ago, there are better options in Asheville now), and the beer specials in C-ville were very good.
The Adams Morgan location seemed to be pricier and lacking selection.
Doesn't the clientele depend on location and time of day?
Quite possibly. I've never been to the Adams Morgan one but have been to RVA and Chapel Hill. It was about a 50-50 blend of hipster-y looking college kids and dudes wearing hemp shirts.
