Not very crowded. Service was quick. Cashier very pleasant. There were chairs/tables fronting area so watched them cook and serve. Restaurant was clean. Fountain drinks were self serve. There were self serve condiments of spicy peppers, ketchup, salt/pepper etc.
The burger was delicious. It had mayo, tomato and lettuce. Will be back when in the area as Hawaii does not have Habit Burger yet. Hopefully soon
