If the server brings out your food to you, yes you tip. It does not have to be much, a dollar or two but if they bring you your food, you should give something, If you go inside and get your food, there is no need to tip. The same theory applies when you get take out from a restaurant like Carrabas- if they bring you your food outside while you wait in your car- give them a dollar or two- not much.
