Burger bakar sounds healthier than Ramly because bakar means grilled, and the patty is genuinely flame-grilled instead of swimming in margarine. But these stalls stack them tall on purpose. You get a thick patty, double cheese, an egg, sometimes beef bacon, all glued together with a heavy special sauce.
So you start with a decent grilled patty and then bury it. A basic single is around 500, but the loaded special with cheese and egg easily hits 720, and the monster double-patty ones the popular stalls sell can clear 900. The grill saves you some oil, the toppings give it all back lah.
