There's the option of calling ahead to place your order for pickup as stated by a previous commenter or you can call ahead to get the wait time and put yourself on the list before you get there. As far as actual reservations a day or so in advance, I believe there is a minimum number of people in your party before you need to do that.
Yes. You don't have to be there to place an order. You are able to call them and let them know you will be coming to pickup your order.
