Did they take reservations

It's not reservations its "call ahead seating" which will just put your name on the list. You still might have to wait to be sat and you most certainly are not guranteed a specefic table you request. They will try to accomodate you if you want a certain table but its not promised.

Yes you can book a reservation. Use there Web site and pre book you table. We have used it and it's perfect you turn up and usually walk right in unless they still setting your table.
