Ive stumbled on this place recently since I went to work very close by, and wanted to recommend it to you all. It is on Twinbrook Pkwy in Rockville, a very short block off Rockville Pike. I have no experience in authentic Argentinean foods, so I can't vouch for that aspect of the place, but I can say that it has some good food.
While they have hot foods and sandwiches, their bakery items seem to be the focus. They have the most wonderful assortment of empanadas, with fillings such as beef/chicken with onions, peppers, and olives; or ham, cheese and eggs; or corn, onions and béchamel; or tuna, onions, parmesan, etc. They also specialize in Tartas (Argentinean quiche) that are beautiful many combinations like a spinach or tuna or ham and cheese. They have incredibly beautiful sweet pastries as well I tried a delicious one today that was sort of a puff pastry roll filled with dulce du leche.
Their prices are great. Lunch specials include a 3-empanada sampler with drink, or a slice of Tarta with soup and drink for under $5. Ive tried their lunch special breaded-fried steak twice (I think its a Milanesa style according to their menu) the first time it was absolutely worth the $7.25 platter price, but today it was tough/chewy and not as well flavored, so I cant definitely recommend their hot food/platters (yet!).
Even though they are open for dinner (and even have a wine list), the atmosphere is strictly lunch oriented. The staff is incredibly friendly and helpful. The clientele is heavily Spanish-speaking. And, they have a terrific selection of imported groceries, from coffee, to spices, to cookies, and the olive-oil mayonnaise that I bought today (Mayoliva approx. 16 oz. pkg for $3.40).
Has anyone else tried this place yet? What do you all think?
