Glad I tried one of the original locations - cute location in the park, gives a very European feel. The ordering/line system works well if you know what you are doing. My mushroom burger was tasty and not too overly fried like other places. Prefer it over Good Stuff Eatery's in DC. Enjoyed the cheese fries and liked that they served beer and wine too. More shake flavors than at the stall in Nationals' park, but that is to be expected for the full service shack.
June 2011: Tried the stand at the National's Ballpark and endured the long lines in the hot sun, only for a small and underwhelming milkshake. Keith had the cheeseburger and although they were all pre-made and just waiting at the counter, the flavor was good. I was not impressed, however I might give the Dupont Circle location a shot.
