Between the Buns

Fast-casual concepts usher in new era of burger innovation.

Burger restaurant concepts use premium ingredients to capture new customers.
Burger 21's Black Bean Burger includes lettuce, tomato, red onion, salsa, avocado, sun-dried tomato aioli, and cilantro cream on a toasted whole-wheat bun.

The combined influence of better-burger restaurants and the fast-casual customization model has had a profound impact on what burger brands now offer consumers. A recent survey by Chicago-based technology and services company Food Genius, which measures menu mentions at restaurant across the U.S., shows that while traditional ingredients like onions, tomatoes, and mushrooms are still the most popular topping options, more unique foods are taking root at burger concepts across the country.
