Osaka is definitely delicious for the money. I've been there twice now and both times the food was of high quality and super delicious. The teppanyaki shows have been enjoyable both times and despite having a similar routine, both cooks managed to make it fun and different.
Our first time in, on my father's birthday, we had no problem being seated during our reserved time slot. However, we returned on Father's Day to wait almost an hour past our reserved time to be seated. Understandable considering it's a holiday, but they should be more careful on overbooking their time slots. It was worth the wait in the end as we all had an enjoyable time and good food, just thought I would mention that holidays might be a bit more packed than advertised.
I haven't had their sushi personally but my two siblings have and say it's delicious. I've had the steak and calamari teppanyaki both times and it's to die for. The calamari especially is flavorful and not at all rubbery like some places, it's so good! Tried the fried gyoza last time and it was also extremely delicious. Great place, would recommend it overall!
