Fatih Akin’sSoul Kitchen is messy, good-natured, and eager to please. Unlike Mostly Martha, Germany’s other restaurant comedy with art-house potential, Akin populates his kitchen with flawed, bizarrely offbeat personalities. There are times when the energy flattens, but Akin and co-writer Adam Bousdoukos redeem the slow moments exasperated performances and jokes that do not dwell on their punch lines. There is also ample assistance from a soundtrack that memorably combines classic soul and European techno. Amidst the broad humor and lovingly-filmed food, there is even insight into how a mediocre restaurant can transform overnight.
