It took about 15 minutes to place the order, as the machine kept deleting our requests... maybe because of the coupons we have tried to apply.
When we got proper help from the staff he managed to screw the order up, typed the wrong kind of meals, didn't use the full coupon code (which had cost us money), and some of the food that we go was burnt (the actuall burger burnt!).
Well, we were hungry and in a hurry. Won't make the same mistake again.
Avoid if you can. If you have no choice.... you'll get something to eat.
(Specific branch. There are other which are far better).
