I'll be spending 3 weeks at the Sheraton Pentagon City for work. I've been there before, and I know there's a good thai restaurant on Columbia Pike, and a Nando's at Pentagon Row.
Where else can I go for dinner? I don't mind taking the metro a few stops in any direction, or walking up to a mile or so. I'm looking for places that are decently healthy, since I'll be eating out 20 nights in a row. Also, I'll generally be eating alone, so places where I can sit at the bar or are very casual would be great. Recommendations for sushi, mexican, thai, korean, big entree salads, etc, are appreciated.
