"A modern regional chain founded in 2011 that helps carry the onion-burger tradition forward, offering cooked-to-order smashed patties topped with a mountain of grilled onions; the menu includes contemporary options like turkey and Impossible meat, and the double-fried, crispy fries and thick chocolate shakes make for a distinctly 2020s take while preserving the juicy, charred-onion flavor people seek." - Amy McCarthy
