Delicious! So good I was here 2 days in a row. The first visit I had the shack stack - oh man is that dangerously good. Lots of cheese. The shakes are creamy, heavy and good (if you're stomach can handle). The fries aren't my favorite but I'm not complaining about fried potatoes. :) I did get a stomach from food / cheese overload but it's ok.
Next day I came back and had a single cheeseburger - so tasty. Hubs loved it and thought it had so much flavor. The creamsicle we'll pass on next time.
