The Burger at The Attic is one of those burgers you can judge on looks alone. A glistening patty of beef that sits atop a pretzel bun stacked with fresh and well thought out ingredients. The full list of ingredients consists of a bakery-fresh pretzel bun, 1/2 pound of juicy beef, spring mix, tomato, chipotle mayo, and your choice of cheese (and you have to add the optional bacon). The burger pairs many complementary flavors and a blend of sweet, savory, and spicy along with the combination of fresh premium ingredients will make your mouth water. I'd personally suggest adding on the bacon and selecting provolone cheese. The chipotle mayo does plenty to bring a little bit of kick for your tastebuds. Egg was offered as an upgrade/option but I believe it wouldn't do much to complement all the veggies on the burger, and it would make the entire burger unmanageable. This gem is like hitting the jackpot... easily the best burger in Phoenix.
