I am in Tokyo in order to fight in Sengoku III. We fight Sunday and won't get done until 11 pm or so. I am looking for a restaurant to take our group of 6 to afterwards. We are in Shinjuku but don't mind traveling 30 minutes or so if the food is worth it. I really like sushi and would most prefer that. I especially love sushi buffets. Otherwise, I am open to tepenyaki or tempura or traditional japanese food. I prefer a more upsclae place but as I said, sushi buffet is most important.
Please any help would be appreciated!
