The Story

Phoenix's award-winning smashburger
Arizona beef, serious crust.

Bad Jimmy's started as a pandemic-era pop-up before chef-owner James Piazza landed a brick-and-mortar on Pierce Street in Downtown Phoenix's Roosevelt Row arts district. What began as a hyper-focused concept - smashburgers, soft serve, and a small-but-serious cocktail program - has grown into the Valley's most-awarded burger brand, with four locations across Phoenix, Scottsdale, Tempe, and Uptown Phoenix. The name fits: there's a rock-and-roll edge to the red neon, the loud soundtrack, and the refusal to take a boring approach to a simple thing.

The Double Burger is the centerpiece: two 80/20 blend patties sourced from K4 Ranch in Prescott, smashed hard against a hot griddle until each one develops a wide halo of caramelized, lacy-edged crust - what judges call the 'wings.' They're layered with Kraft American cheese, griddled onions rendered in beef fat, crisp pickles, and the Not-So-Secret Sauce, a Kewpie mayo-based Thousand Island that brings a Japanese-leaning richness. Everything lands on a Martin's potato bun. It won Phoenix Magazine's smash burger taste test in 2024 and the Arizona Restaurant Association's Most Crave-Worthy Burger award in 2025.

Smash Atlas Context Note

Bad Jimmy's is a burger-forward restaurant with cocktails, natural wines, and soft serve. The Smash Score reflects the Double Burger and burger-specific praise, not the entire bar or dessert program.

The Double Burger is the flagship item that won the 2025 Arizona Restaurant Association Foodist Award for Most Crave-Worthy Burger. Chef-owner James Piazza emphasizes 80/20 fat-content beef for optimal smash results - the high fat content creates the 'lacy halo of caramelized crispness' around each patty that critics and diners consistently call out. The Not-So-Secret Sauce uses Kewpie Japanese mayonnaise as its base, giving it a distinct richness versus standard Thousand Island. Griddled onions are rendered in beef fat. The Classic Double ($12) is also available with raw onions, ketchup, mustard, and pickles for a more traditional build.

What Critics & Diners Say

Review Excerpts

"

Bad Jimmy's won the Best Smashburgers award: 'The more perfectly seasoned, crisp-edged burgers served with crunchy waffle fries, the better.'

Phoenix New Times - Best of Phoenix 2025
"

The bread-to-patty is perfect. The crispy edges - the 'wings' - are the most important element of an authentic smash burger, and Bad Jimmy's nails them.

Phoenix Magazine - Best of the Valley Taste Test 2024
"

This burger opened my eyes to what a burger was meant to be. Less pretension, more Maillard reaction.

Hall of Yum
"

It wasn't overly salty or overcooked like a lot of smash burgs can be. Ranked among the best burgers I've had in Chicago. Score: 9.6/10.

Burger Boyz
"

Bad Jimmy's is basically the tattooed version of your classic American burger joint - a little rebellious, kind of loud, and always fun after dark.

The Infatuation Phoenix
"

THE must-hit burger destination in Arizona. Arizona's hottest burger joint.

A Taste of AZ
"

Biting into one would evoke memories of every sauce-dripping, paper-wrapped burger that you ate as a kid, but better. The delectable halo of caramelized crispness around the patty makes it something special.

Phoenix Magazine - Press Corps
"

Fine burgers with thin, crunchy-edged patties. The waffle fries are exceptional - right up there with the best in the Valley. The no-modification policy can be frustrating.
