For more than 30 years, Niko Niko's has been offering up authentic Greek food, many of the recipes coming from founder Eleni Fetokakis's father's restaurant in Athens. A converted gas station, Niko Niko's is always bustling with diners eager to get their Greek on. Customers form a line at the counter and fire their orders off into one of the most prolific kitchens in town. Gyros served in warm puffy pita with sweet onions, juicy kabobs and Greek salads served with a large slab of feta are just some of the reasons why Houston has embraced Niko Niko's as one of its favorite family-owned joints.
