William Singer opened the first Royal Castle in 1938. Burgers came round instead of square, topped with onions and pickles. You could wash them down with Castle Cola or birch beer ( which is different than root beer, by the way). The menu had more than just burgers - eggs cooked in butter, toast with jelly, bacon, and grits. You could also get fries, shakes, chili, donuts, and a giant fish sandwich with tartar sauce.
For children of the 90s Boston Market always seemed like a beacon of homestyle cooking amid a sea of cheap burgers, but that reputation hasn't saved the chain from collapsing in recent years. Founded in 1985 as Boston Chicken in the Massachusetts village of Newtonville, the restaurant was imagined as a healthy, higher-end alternative to normal fast food. In some ways it was on the leading edge of "fast casual" dining, offering something closer to home cooked food but with the speed and prices of fast food.
