It’s fiesta time, Oak Brook! Fat Rosie’s, the vibrant, high-energy Mexican taco and tequila bar known for its over-the-top fun, is opened its newest location at 3011 Butterfield Rd., Suite B101 in Oak Brook on Friday, May 23, 2025.
Spanning over 7,000 square feet, the Oak Brook location will feature two patios, a private event space, live music, and all the bold flavors that Fat Rosie’s guests have come to love.
Embracing the motto, “Fluent in Fiesta,” every Fat Rosie’s location is designed to turn a casual night into an unforgettable celebration. Guests can expect authentic decor straight from Mexico, including alebrijes (hand-painted, brightly colored Mexican folk art of animals), a thatched roof palapa, and custom art throughout the restaurant.
The menu? Think traditional Mexican cuisine with a fun and modern take! Featuring authentic flavors, the kitchen serves up favorites like chips and dips, tacos and tamales, plus bolder menu items like sizzling Kick-Ass Fajitas, the legendary El Patron Gordo Burrito (a larger-than-life 3 lb. stuffed burrito…finish it in 12 minutes or less and it’s free!), and new additions like Fiesta Nachos. Behind the bar, the drink menu starts with a lineup of Ass-Kickin’ Margaritas (yes, that’s trademarked), and signature cocktails like the spicy-smooth Pepino Picoso, the vibrant Paloma Rosa, and Fat Rosie’s own Michelada Chingona made with their locally-brewed Chingona Lager – plus, frozen margs, a full lineup of tequilas and cervezas, and newly added mocktails!
“We’re beyond excited to bring the infamous Fat Rosie’s energy to Oak Brook,” says CEO John Iannucci in a statement. “It’s a lively, welcoming community with a mix of families and corporate crowds, perfect for a place like ours where you can host an energy-filled birthday dinner one night and a business lunch the next day. We can’t wait to share our version of a Mexican fiesta with the neighborhood.”
Fat Rosie’s Oak Brook marks the brand’s seventh location in Illinois, joining Naperville, Schaumburg, Frankfort, Lincolnshire, Lincolnwood, and the most recent opening in Rosemont. Fat Rosie’s also has plans to expand its footprint outside of Illinois later this year.
