my family of 4 walked to this restaurant after walking thru the Carnegie Museums. Parking downtown is awful. simply awful. But the walk from the museums to Stack'd wasn't too far. we were seated immediately. We all chose the build your own burger. I will say that they don't put alot of each topping on your burger. Like my son had 4 fritos on his.That being said, the burgers were awesome. Filling, juicy, good seasoning. Service was good. prices fair. Tip: look at the menu online ahead of time to get an idea of the choice of toppings.
