Not to butt in, but I can highly, highly recommend Ray's to the Third, on Wilson about halfway between Courthouse and Rosslyn stations, as having one of the best burgers I've ever had (it's a descendant of the original Ray's Hell Burger). Hint to those walking: go to Courthouse, as it'll be a downhill walk to the restaurant...when leaving the restaurant, you can keep walking downhill to the east to Rosslyn. (Trust me, I know this from personal experience.)

Esteemed FlyerTalker CMK10 is a fan of Hard Times, straight across the street from the escalators up from the Clarendon station. I assume you guys haven't been, since GoingAway was not familiar with it. Burgers are good but nothing spectacular, but they have several selections of chili to top your items with. Mmm.

Wish I could join, but I'll be in BUR for a family wedding while you're munching away. Enjoy!
