Previous meals at Mrs. K's Toll House restaurant on Colesville Road (Route 29) just inside the Beltway in Silver Spring have left me unimpressed. Made me think of Howard Johnson's food. This time, though, I was pleasantly surprised. A starter of cream of asparagus soup, while salty enough to almost raise one's blood pressure, was still comforting and had nice bites of asparagus in it. Better were entrees of a smoked salmon sandwich in a bagel, the salmon not too salty and nice and smokey, the accompanying fries ordinary, and pan seared arctic char. The arctic char, a fish similar to salmon, although drowned in a (tasty) lemon/butter sauce (I spooned most of it off onto another plate), was seared to a perfect tenderness that showed off the subtle flavor of the fish. The haricots verts and carrots that accompanied the char were cooked to a nice crispness and there was also some very flavorful, crunchy wild rice served with the entree. Our server was attentive, friendly, and professional. Go to Mrs. K's at lunch time when you can look out the big windows that surround the restaurant, some of which look out onto homes and yards. Nice, genteel atmosphere and plenty of free parking.
