This restaurant's building is a historical site and has a very close association with Abraham Lincoln. The food quality is very average but the portion is quite big.

I recently had my friends baby shower at the Grill at the Mansion. We had about 30 people show up. The staff and food was wonderful, everyone loved the history behind the mansion, the beautiful atmosphere, and how perfect it was for the occasion. We weren't too far from each other and yet we weren't so close together you couldn't... More

I am not easily impressed. My daughter became engaged, & the hunt was on to find a venue for an elegant wedding. The couple looked all over, but found no fit. Where can a historic, affordable, outdoor-indoor venue with fabulous food be found? For us it was The Grille at the Mansion! Kathy is brilliant & whatever you need, she... More

My husband took me to the mansion for Valentine's Day. The food was excellent. The service was great. The restaurant has so much character. The only reason that it got 4 out of 5 stars is the price. It is expensive, but worth it.

Outstanding service and historic exquisite atmosphere! We held a small dinner party in celebration of my mom's birthday.

Would highly recommend for your special... More

Been there twice. Both times the service was so-so and the steaks were ok. My wife's was plain overcooked last time and the potatoes weren't really hot. Nothing you'd really worry about at a mediocre chain steakhouse. But for the price at The Mansion, I expected better.

We are seafood, steak and pasta restaurant with creative feature dishes. Jerry Conway is the co-owner and executive chef at The Mansion. He has worked at many fine dining establishments in his 25 years of being a chef, most notably he owned and operated The Cypress Room in Crystal River Florida and was an executive chef at Disney World. At Disney he was in charge of Epcot, The Magic Kingdom, The Royal Floridian and Disney's annual Wine and Cheese Festival. Chef Conway has had several recipes patented and became famous for his Sicilian Steak and Shea-Crab Soup at The Cypress Room, both of which are offered as Specials at The Mansion. The Mansion was built in 1857 by A.J. Wastfield, an independently wealthy farmer who built it for his fiance Elisie Osbourn of Lebanon. AJ's passion was politics, Abraham Lincoln was their most notable guest at their home. The Mansion was a stop on the underground railroad, the removable stairs that lead to the widows peak still remain as a reminder. At the age of 37 tragedy struck when A.J. Was fatally injured in a threshing machine accident on Nov. 15, 1866. He was survived by his wife and two young children, Walter and Julia. Elisie and her children continued to live in the Mansion for many years. The Mansion is currently owned and operated by Kathy Cox and Jerry Conway. The Mansion received a St. Clair County Landmark Award in 1963 from the St. Clair County Historical Society. Please come by and see what we have to offer, you will be glad you did! We are very proud of The Mansion and the history behind it. If you are interested in a short tour of The Mansion after your meal, please ask your server.
