Gazen Ariake is a Japanese dining spot a walk from Kokusai-tenjijo Station near Tokyo Big Sight, serving seafood rice bowls, sushi, and fried dishes. The menu covers seafood donburi, sushi, tempura, and udon, with tempura fried to order. The interior is large and divided into semi-private seating areas. Staff are not fluent in handling foreign guests or speaking English, so ordering can go wrong.
