Do they take reservations for hibachi chef dinner.......you know the large group around the grilling station ???

no reservations needed. about 10 ppl.

Yes

They take reservations but you can't sit until everyone is there.

They're usually not that packed whenever I go but you can call.

I am not sure but you can call them, I only had a party of 3, and there was no wait.

I'm not sure if they take reservations .just give them a call.they probably do
