This was my first time trying Shake Shack ever, and I have to say this was probably THEE best fast food burger I've ever had.
Food: I ordered the Roadside Shack and it's basically a cheeseburger with grilled onions and bacon bits but I also added lettuce and pickles. The very first thing I noticed was the superb quality of the meat--so fresh and flavorful just by itself. I love how all of the ingredients mixed very well together in unison and complimented each other. The burger was absolutely delicious. I also was able to try the Smoke Shack, which I actually liked better than the burger I ordered. At first I thought that the cherry peppers and bacon would overwhelm the flavor of the burger, but it was just so perfect.
Service: Everyone was very helpful and attentive. While we were still deciding on what to order, one of the workers (I think he may be the manager or some type of higher-up) gave us a sample of their Frankenstein (Shackenstein) dessert, which was delicious. Mark also gave us an amazing experience by talking to us while we were seated and cleaning after our trays (we went for seconds and dessert).
Great place for burgers, I'm so happy they're in Summerlin. A MUST try!
