I've never visited the MD location. The VA location is in strip-mall hell.
I have mixed feelings about mixed-use development. In theory, it's great - put shopping, dining, work, and homes in one place. Reduce driving, make walking/cycling possible, etc.
My problem is the way the US approaches mixed-use continues to be at a "larger than human" scale. It's not organic - it ends up being super-blocks developed in one go by a faceless developer. The common spaces tend not to be used - they look good in architecture drawings, but don't work well in meat-space. And parking lots are still built, which creates a Potemkin Village effect (multi-story garage surrounded in fake building facades, etc).
