They opened a Shake Shack in Atlanta but I haven't had a chance to go. I've been watching their stock and it's interesting how hot the fast food restaurant stocks are right now. I think that bubble is more interesting than the actual food itself.
McDonald is testing out "Create your taste" burgers at select locations. You pick your patties, bread, toppings, type of cheese, and sauce. I had the default Cali style burger with guacamole and corn chips on the burger and it was pretty good. But you can custom create just about any burger you want. You get a beeper and the server brings the burger to your table. They put the burger and fries in separate metal wire baskets. I don't think it's going to work as it's far too complicated to retrain your average McDonald's customer but the company seems to acknowledge the premium fast food casual market and is trying to adapt.
