Suggested Lunch Stops "Near" Washington, D.C.?

Well, our upcoming trip to Dulles has been expanded. Weather permitting,
we'll be leaving this coming Wednesday, heading up to Door County, WI,
spending the night there, and proceeding up to Mackinac Island on Thursday
for brunch. From there we ill be heading direct to the Washington, D.C.
area, over the top of the Great Lakes.

It ought to be a beautiful trip!

This routing would mean approaching Washington from the north instead of the
west. I plan to stop short of the ADIZ for lunch, get all of my ducks in a
row with an ADIZ flight plan, and then have a (relatively) short flight into
Dulles from there. (Margy, will arriving on Thursday work, or do I have to
wait till Friday?)

ANYWAY -- it appears that I've got quite a few good choices for stopping --
but maybe you "local" guys can steer me to the best food? I've picked a
few that are right on my flight plan, but I'm open to suggestions:

1. Bedford, PA (KMHZ) is just 35 minutes from Dulles.
2. Cumberland, MD (KCBE) is just 30 minutes from Dulles
3. Martinsburg, WV (KMRB) is just 15 minutes from Dulles

Of these three, which would you recommend? Or, alternatively, what's a
better stop?

Also, I have just started researching this ADIZ flight plan stuff. One
fellow who wrote me off-line referred to "VOR gateways" into the ADIZ, which
implies that there are set "routes" via VORs through the ADIZ into Dulles.
Is this correct, or (once I've been assigned a discrete squawk code and have
my ADIZ flight plan activated) can I fly GPS direct from the point where I
enter the ADIZ straight into Dulles?

Thanks for your help!
