As a corporate pilot, I have eaten burgers all across the globe from Hong Kong to Burkina Faso I consider myself an international burger connoisseur. Many of the restaurants I've visited advertise 'voted best burger' only to turn out to be flavorless or dry necessitating drowning it in ketchup to make it palatable.
Many places can get it right once but I don't consider a place 'great' unless it can produce the same quality on a consistent basis. I have been to the district 3 times and each time I order the same thing and it has been excellent. The burger is full of flavor and the bun is fresh. If you are looking for a great burger in the Phoenix area, there is no other place to go. I put the districts burger in my top 10 best for burgers anywhere in the world.
