Overall the Shackburger (the signature item) is not bad, it's nicer than your typical Macs cheeseburger, but not very worth the price in my opinion. It's the "once is enough" kind of feeling. Get the Double Shackburger so the ratio of meat to bun (and other toppings) is just nice. Also, it would be much better if the meat patty was juicier, or if there was a crunch and bite to the texture.

Which is why I preferred the Shroom Burger, which doesn't contain meat but is nicer than the Shackburger. The mushroom was very juicy (the juice squirted out with every bite, and with the cheese pull, when eaten hot it was very delicious). And there was crunchy fried bits added as well, so in my opinion, this was the better item.
