Hey Glenn!

I'd offer to host you while you're here (I'm only about 20 min from Tyson's Corner) but I'll be in Hawaii that weekend.

Lots of options in the Tyson's Corner area, both in the two large Malls, several shopping centers, and elsewhere. If you don't anything you like, take Rt 123 South into Vienna - again lots of choices.

If you have a preferred type of food (or chain restaurant) ask and I'll see what is available. Plenty of "healthy" food options as well.
