What people say
Fat Rosie's Taco and Tequila Bar on Butterfield Road B101 in Oak Brook brings the kind of bold, feel-good Mexican energy that keeps people coming back. Known as a loud and proud Chicagoland favorite since 2015, the restaurant carries that same Fiesta-forward spirit into its Oak Brook location, making it an easy pick for anyone craving vibrant flavors and a lively atmosphere.
The bar program is a standout, with margaritas that are front and center and a fun, celebratory vibe throughout the space. Whether you’re stopping in for drinks with friends or planning a meal that feels like an event, Fat Rosie’s delivers on both taste and mood—cheerful service, great food, and plenty of reasons to raise a glass.
Fat Rosie’s also leans into the “family memories” side of dining. It’s the sort of place where occasions feel more memorable simply because the experience is so welcoming and upbeat. From casual get-togethers to special celebrations, it consistently nails the balance of comfort and excitement—Mexican favorites done right, paired with tequila-fueled fun.
