Assuming you mean the haunted house portion during Halloween, not terribly. Depends on your tolerance for jump scares (people jumping out of the shadows), The rest of the place during the normal year, It's not scary at all, absolutely gorgeous, despite rumors of paranormal activity.
Had dinner there for new years the place has some strange vibes and an ominous feeling to it.
The Lemp Mansion is a restaurant and wedding venue with a lot of history. Many people go for dinner and don't consider it scary at all, others have reported all sorts of unusual and or unexplained events during visits. If you are referring to the Lemp's Brewery haunted house the takes place around Halloween is is not associated with the Lemp Mansion and is like other commercial haunted houses so that might be a guide.
It was not scary at all to me to be honest.they try to make it scary,but it is just old looking with some weird old photos.Obvious ghost cameras are all around. The creepiest part was our host/waiter leaving us on the third floor when we turned out backs quietly 😂.other than that it is cool
