RPM Seafood is the Lettuce Entertain You and Bill/Giuliana Rancic RPM group’s glass-walled seafood restaurant on the Chicago River, serving pristine raw bar selections, whole-roasted fish, and Dover sole carved tableside with panoramic river views. Opened in 2020 at 321 N. Clark, it’s a polished power-dining destination where the sleek design and waterfront setting match the premium price point.
