Ian Froeb’s STL 100: The best St. Louis restaurants of 2026
St. Louis Post-Dispatch | April 10, 2026
Don't let the eponymous mansion of August the Mansion intimidate you. Yes, this O'Fallon, Illinois, restaurant occupies a grand historical home, and its dining rooms cushion you with cozy elegance. But thanks to its spacious, casual lounge, August the Mansion welcomes spur-of-the-moment visits as well as destination-dining reservations. Chef Jessica Hickman's thoughtful seasonal cooking meets you wherever you sit. You can appreciate her Cornish game hen with haricot verts in jus as a more refined roast chicken - or you can tear the bird apart with your hands to get every last morsel and soak up the jus with homey cornbread stuffing. Hickman deftly balances big chops and crispy bites of boudin sausage, Brussels sprouts and burgers, and since last year August the Mansion has opened for weekday lunch as well as dinner.
