Delicious burgers, lots of options, huge portions (all burgers have double patties and you can add all kinds of toppings) and great taste.
They have milkshakes and also a variety of local beers on tap.
I'd give them 5 stars but the place is always packed and it's really a pain to find a seat, especially if the patio is not open. Also the waiting time can be very long, when I was already eating my meal they put a sign at the door warning customers about the 1 hour wait for the food.
