Sullivan's Steakhouse

In Naperville, Sullivan's Steakhouse is best understood as an upscale American steakhouse and seafood restaurant for diners who want a classic steakhouse meal rather than an experimental format. The essentials are direct: a business-casual dress code, an estimated spend of about $100 per person, daily hours that run from 11 AM to 10 PM Sunday through Thursday and until 11 PM on Friday and Saturday.

The cooking is built around familiar steakhouse and seafood choices. Signature dishes include Filet Mignon, New York Strip, Bone-In Ribeye, Beef Wellington bites, Cheesesteak Eggrolls, Shrimp & Lobster Bisque. That makes the appeal clear: this is a place to consider for steakhouse comfort, recognizable dishes, seafood alongside the beef-focused order.

At about $100 per person, the value depends on wanting an upscale steakhouse experience with signatures such as Filet Mignon, New York Strip, Bone-In Ribeye, Beef Wellington bites, Cheesesteak Eggrolls, Shrimp & Lobster Bisque.
