"Giant Drive-In, in Lake Oswego, serves classic burgers with a multitude of toppings out of an A-frame burger shack off Boones Ferry Road. The extensive burger menu ranges from the standard quarter-pound burger to a massive creation called The Filler: bacon, cheese, ham, two burger patties, egg, lettuce, tomato, pickles, and sauce teetering between two soft burger buns. Giant accepts cash only." - Rachel Pinsky
