Yet another outstanding smash burger to add to the list. This one from pop-up about town, Chubby Boy's Burgers. They were at Ludlow Liquors last night for this week's iteration of Mike Sula's/Chicago Reader's
Monday Night Foodball series.

The Original Chubby has two juicy smash patties topped with béarnaise aioli, savory hot honey bacon, crispy fried onions, and pickled cherry peppers, all on a Martin's potato bun. Beefy, rich, fatty but with a kick and some crunch. Just great.
The Oklahoma Patty Melt, an extra oniony sandwich starring the same great patties as the Original Chubby, was also pretty great.
Strongly recommend dropping in next time you hear about them popping up. Seems like Instagram is the only way to stay in the loop:
