Will sit-down restaurants let you just walk in and order an item for carry-out without sitting down? If I wanted, say, a piece of cake from a certain location or a certain appetizer or some such to take out and eat while watching a parade or just sitting on a bench, will they do that without me going in as if I'm ordering a whole meal? I'd hate to take up my time and take a table from someone else for something that could be so quick......
