Kielbasa Factory is a Polish deli serving kielbasa, pierogi, and other specialty foods from the old country, and regulars say this Rockville shop is among the best ethnic eateries in town.
If you visit during the lunch hour, you're likely to find office workers lined up for this place's famous Polish sandwiches (regulars suggest you order yours on rye with sauerkraut and mustard), and for the full experience, add a couple of pierogies to your order in your choice of potato, onion, or cheese. If you swing by earlier in the day, you'll find folks ordering cinnamon buns and doughnuts by the dozen. Bring a box to work and you'll be the most popular person in the office! Keep in mind that in addition to offering prepared foods, Kielbasa Factory also serves as a small grocery where you can stock up on smoked meats and cheese, as well as Kinder chocolates, wine, and other treats.
