Any sidewalk-stationed food cart can either be a hidden treasure of unique flavor or an unfortunate deception that will have you nursing a bottle of Pepto for the rest of the day. OFF’s new movie Street Food is of the former genre--a succulent smorgasboard of urban treats that goes down smoothly. The Finnish film is baked with a zesty list of fresh, organic foodstuffs, including cups of Joona Saikkonen, Atte Permikangas, and Alex Saikkonen; tablespoons of Iiro Permikangas,  Joonas Eloranta, and Topias Paaso; and whimsical dashes of Joel Liedes, Sakarias Paaso, and Petrus Saikkonen. Dig in.
