What's the best burger from The Burger Junction, Edappally (TBJ)?

Had a double cheeseburger from the Panampilly one and felt like maybe I should've added extra topping on it. What toppings should I add if I do order a burger from there?

EDIT: After reading the comments most recommended ones are the Haystack and the Baconator, followed by TBJ Special Beef & Verde. I guess I'll be trying those next time I go there. Thanks!
