This is hands down, the best burger restaurant I've been to. The BEST burger I have eaten.
You go in, order the size of your patty, and decide if you want one or two patties. You chose your bread and your cheese. Done... for now. You watch the patty being cooked right in fornt of you.
You pay (cash only), take your burger to the ingredient table. Then you put in the ingredients that you want into your burger. Whatever you want, and how much you want of it... but play fair!
I used to go here on a weekly basis when I lived close to it, now I live further, but I still make sure that I visit my favorite burger place ever.
200% recommended!
