Get extra jalapenos, beetroot, lettuce, pickles, tomatoes, onions and sauces on the new Gourmet Creations burgers at no additional cost.
Just use the self-order kiosk to add a Gourmet Creations burger. Then select 'Edit' and the burger again. Now add extra cheese, etc. Does not work with other burger types.
Update: Appears extra cheese is no longer free. Looks like it may have been a pricing error. All other free extras still work.
I have always been able to this. Isn't it just a normal thing and not new?
