Hi! I've tried for months to get a reservation for four to have dessert at Beaches and Cream (specifically the Kitchen Sink which I know they don't sell at their walk up window). I'm headed down next week and I wonder if it will be worth our while to just show up and wait? Do they typically allow walk ups? I don't mind waiting but don't want to not even have an option to wait as we will be going out of our way to get there. TIA!
