You can do call ahead, which in itself it pointless. They are reluctant to seat a party if everyone is not present. The place is busy so I get it, at the same time the staff needs to be empowered to make better decisions. For us we spend alot of $$ and if we are seated right away the ticket cost goes up and everyone wins, if not it is just super inconvenient.
I don't think they check this site on a regular basis. You should contact them directly.
