On a conceptional level, Hero Burger works.
Construct the burger as you want it. They offer a wider selection of toppings, many of which you would find on a gourmet burger. You pay a premium on some of the better cheeses ... but ultimately you're customizing the burger as you want it. The smell of patties is intoxicating.
The only draw backs i have for this place is sometimes ingredients taste cold. I guess when you have so many ingredients you have to have them in a fridge so that they don't spoil but it takes away from experience of what a burger should be... comfort food (since when is anything about a burger cold?) Ultimately your burger cook will often forget to put the toppings on the grill to heat up to the temperature it should be.
I figure burgers are also put on the frozen because of the amount of time it takes to prepare the burgers.
The other draw back is the price... but that is because you're buying essentially purchasing a gourmet burger.
I'd recommend trying Hero Burger as a treat, make sure you tell your cashier to relay that you want your ingredients hot and it will help with your experience.
