Funny I should suggest going to a Scottish restaurant like McDonalds on Whiele Avenue in (officepark laden) Reston for the fries, but it's true. I have eaten several dishes there which, while good (particularly the dishes from the "Beef specialties" list, like fluffy sesame seed buns stuffed with two all beef patties, and the single beef patty in a mayonaise/ketchup sauce with a crisp, green pickle), aren't as scrumptious as the long, slender potato fries that the chef expertly coats with fine, idodized salt. (Word of warning though: the servers, while efficient and friendly in a glazed, factory-worker sort of manner, were assertively pushy in rushing me to provide my order before Id had a chance to adequately peruse the menu.) The Scottish appellation of the establishment may be a bit misleading because their true specialty is more Irish in origin (or, depending upon how you want to consider the matter, South American, Belgian, or French) leading to some initial, though temporary, confusion when confronting the convenient, well-lit, menu. The pomme frite are thin and crispy when fresh from the fryer (which the management has thoughtfully positioned so that the diner can watch the precise, grease-laden frying process) but can become soggy and lifeless if allowed to sit on the plate too long. You must also choose your dining companions carefully at this location (and make sure they all order the pomme frite) or you may find your greasy, starchy morsels snatched from your plate the moment your head is turned. You can actually taste the potato unlike some pomme frite and the salt is terrific without being overpowering. McDonalds also does carryout. McDonalds also has nice outdoor tables and Whiele Avenue, fortunately is a busy street without any construction going on so one could imagine oneself dining alfresco in a European city, like Luxemborg City, which has the same acrid, overwhelming diesel aroma lingering in the air.
