Fat Rosie's Taco & Tequila Bar is a Chicagoland favorite, established in 2015 after a chance encounter in Mexico. It offers a loud and proud Mexican dining experience across multiple locations including Frankfort, Naperville, Schaumburg, Lincolnshire, Lincolnwood, Rosemont, and Oak Brook. Guests can enjoy diverse menus for dinner, drinks, lunch, brunch, happy hour, and quarterly features.

The restaurant also provides convenient online ordering for curbside pickup and delivery, as well as services for parties and catering.
