Yes
Yes of course they have a party room for that. That would be very considerate for everyone eles at any restaurant.
They do not take reservations but they will place you on list with a phone call as Angela has posted. We called, got the estimated waiting time for our party size and calculated when to arrive. We only had a 5 minute wait. Well done, no pun intended.
They do accept calls to get on wait list. Or you can complete online.
