It's always a great time at Osaka! Just make sure you're okay with loud drum sounds and people singing happy birthday...
My family and I have been here a few times now and so far we have found the food to be consistent. Teppanyaki is such a fun time. The show is exciting and they squirt sake shots at you. I guess it's typical but our chef really did a great job. He cooked our meat to the correct temperature while entertaining us. I mean, talk about multitasking.
If you only wanted sushi, they do have minimal seating areas for that near the bar. Make sure to try the yellowtail carpaccio and the fat boy roll. You can't go wrong with those!
Service have been and hit and miss but nothing we wouldn't come back for. Minor issues like water refill etc.
Overall, if you're looking to have fun and be in a loud atmosphere then definitely try this place.
