Description: We are steak and seafood restaurant with creative feature dishes. Jerry...
We are steak and seafood 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.

Nice hidden Secret

Visited for Lunch, it was a beautiful place. The owner came out and talked to us, the food was delish and the Tres Leche (3 milk )cake was to die for.

My wife and I have been regulars with Paulo and David at the Mansion for over 6 years. We understand they moved on and there are new opportunities for the Mansion with the new owners.

Chris, First I would like to thank you for trying the restaurant after Paulo and David left. We are trying to maintain the high quality with the local touches.

We recently visited The Mansion to celebrate my husband's 40th birthday. Being new to the area, I suggested this restaurant based on the glowing reviews from trip advisor. Crab cakes were our starter: fresh and full of crab, although a bit bland on the palette. Then delightful little salads were served with a lovely and very light dressing. Next came... More

First, this is an expensive restaurant. They changed their menu the night we dined actually. It is more expensive than the menu found online. Expect to pay $100-$300 on average for 3 courses and drinks for a couple. Second, we had three problems with the restaurant. The first was the lamb. My wife, being British and lamb being a staple...

Always great service and great food! The restaurant is an old house. It is tucked away off the highway. You have to be careful or you may drive by. The martini's are great!

I went there for a dinning "experience" with my parents and that's exactly what we got. An experience. The food is far superior than what you would expect to find in a smaller town.

We eat here fairly frequently. The staff is excellent and well trained. Never heard a complaint from friends, family or colleagues. The sirloin with mama butter and bread pudding are my favorite. Love sitting by the fireplace in the winter. They have multiple rooms, great for private events.
