REVIEWS
The Shack Stack is seriously filling. Combining a beef patty with the fried mushroom is a bold move, but it works really well. You get that juicy meat flavor plus the crispy, cheesy mushroom in every bite. Definitely not a light meal, but very satisfying.
—Brandon Lewis
I liked the mix of textures in this burger. The beef is juicy, and the ’shroom patty adds a crispy, cheesy layer that makes it different from anything else on the menu. It’s a bit messy to eat, but the flavor makes up for it.
—Megan Foster
This burger feels like the best of both worlds. You get the classic beef taste along with that rich, cheesy mushroom filling. It’s quite heavy, so I’d only get it when I’m really hungry, but the taste is worth it.
