No reservations are accepted. It's classified as fast food, so it's buy and dine. They do have phone-in service for pickup.
Even on busy days the order line is fast, and the food comes out quickly as well. I go to Crown Burgers for lunch whenever I get the chance.
You just walk in, order, and seat yourself. It shouldn't be overly crowded - you won't have trouble getting a seat/table.
