If you don’t think of Rio de Janeiro as the spot for finding the perfect Japanese food, then let the Koni Store’s two locations change your mind. This popular Japanese chain sells popular oriental entrees that taste totally authentic. Some of the favorites of the locals and visitors include their sushi and temakis, both served in rolls. The operating style here and layout of the restaurant are similar to fast food restaurants. So is the speed of the service. However, the food is far superior to a Big Mac or Whopper.
