Sold in combo with a generous portion of good fries and an unlimited refill soft drink, about 8 bucks. The default on doneness of the burger seemed to be medium, which was just right. Order and pay at the counter and they will bring your food to your table in a jiffy. Home-y, kitschy ambiance and no little screaming kids running around.
