Shamshiry is a sit down Persian restaurant located in what appears to be a nondescript office park in the middle of Tyson's Corner. I ordered the salmon kebabs with scented rice. The salmon was well-seasoned, if a little well done and dry for my taste. The scented rice, on the other hand, was intriguing. It was perfumed with dill, which you could smell as you took a forkful of rice and put it in your mouth. It was actually fascinating because the aroma of the rice enhanced the flavor of the salmon as a whole (an interesting example of the olfactory sense affecting one's taste, much like a fine wine's flavor being enhanced when you inhale deeply from your glass while sipping the wine). Slivers of fava beans were also mixed into the rice, giving the dish some welcome heft and heartiness.
In sum, I am not sure this is worth a detour to go to, but the food was generally well done. The rice was the best part of the meal and I would be interested in coming back one day and trying out some of their other rice dishes.
